Scandium Metal Sc Metal CAS 7440-20-2

About Scandium Metal Sc Metal:
Scandium is a chemical element with the element symbol Sc and an atomic number of 21. Is scandium a metal? A silvery metal that tarnishes in air, burns easily and reacts with water. Scandium is mainly used for research purposes. It has, however, great potential because it has almost as low a density as aluminum and a much higher melting point. Elemental is a soft, silvery-white transition metal, often mixed with gadolinium, erbium and other existence, the yield is very small, in the earth’s crust content is about 0.0005%. Why is scandium so expensive? Owing to its scarcity and limited production, scandium is one of the most expensive of all the natural elements.
Is scandium harmful to humans? Health effects of scandium: Scandium is most dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. This can cause lung embolisms, especially during long-term exposure. Scandium can be a threat to the liver when it accumulates in the human body.
Scandium is commonly used to make special glass, light and high-temperature resistant alloys. Scandium is slightly yellowish or pink when oxidized by air, is easily weathered and slowly dissolves in most dilute acids. However, in strong acids, the surface tends to form an impermeable passivation layer, so it does not react with a 1:1 mixture of nitric acid (HNO3) and hydrofluoric acid (HF). Tungstenmolybdenummetals is a trusted global Scandium Metal Sc Metal supplier. Feel free to send an inquiry about the latest price of Scandium Metal Sc Metal at any time.

Product Performance of Scandium Metal Sc Metal  CAS 7440-20-2 :

The scandium metal is silver-white, generally distilling crystalline lump (meat-like) metal, and the ingot, sponge block or lens can also be button-shaped as-cast with a clean surface. It has a melting point of 1541 °C and a boiling point of 2831 °C. Scandium metal is easy to dissolve in water and can interact with hot water, making it easy to darken in the air.

Product NameMFPurityParticle SizeMolecular WeightDensityColor
Scandium MetalSc99.9%- 99.999%100 mesh44.9562.985 g/cm3Silver White 

 

How is Scandium Metal Sc Metal Produced? 
The pure yield of scandium can reach 94%, the crude scandium contains 92% of scandium, the main impurity Ta_7 ~ 8%, Ca 0.5%. The use times of tantalum crucible were increased by this method. Pure scandium can be prepared by distilling the crude scandium obtained by reduction in a tantalum crucible with a thickness of 1 mm and a diameter of 40 mm. Ta in scandium can be reduced to 0.02%, and the purity of scandium is greater than 99%.
 
Applications of Scandium Metal Sc Metal:
Scandium is used in aluminum-scandium alloys for aerospace industry components and for sports equipment such as bicycle frames, fishing rods, golf iron shafts and baseball bats. Scandium iodide is used in mercury vapor lamps, which are used to replicate sunlight in studios for the film and television industry. What is scandium used for in the world?
Lighting industry
Scandium sodium lamp has the characteristics of high luminous efficiency, good light color, power saving, long service life and strong ability to break fog so that it can be widely used in television camera and square, stadium, street lighting, known as the third generation of the light source. In the metal-insulator-semiconductor silicon photocell and solar cell, scandium is the best barrier metal.
Alloy industrial
Scandium, in its elemental form, has been widely used in the doping of aluminum alloys. As long as a few thousandths of scandium is added to aluminum, a new phase of Al3Sc will be formed, which will have metamorphism on aluminum alloy and make the structure and properties of the alloy change significantly. The addition of 0.2%~0.4% Sc can increase the recrystallization temperature of the alloy by 150~200℃, and the high-temperature strength, structural stability, welding property and corrosion resistance are obviously improved and can avoid the embrittlement phenomenon which is easy to occur in the long-term working at high temperature.
To change the agent
Scandium is also an excellent iron modifier. A small amount of Scandium can significantly improve the strength and hardness of cast iron. In addition, scandium can also be used as an additive in high-temperature tungsten and chromium alloys.
Ceramic materials
The elemental scandium is generally used in alloys, and the oxide of scandium also plays an important role in ceramic materials. Tetragonal zirconia ceramics, such as those that can be used as electrode materials for solid oxide fuel cells, have a very special property in which the conductance of this electrolyte increases with temperature and oxygen concentration in the environment.
The catalytic chemistry
In the chemical industry, scandium is often used as a catalyst, SC2O3 can be used for ethanol or isopropanol dehydration and deoxygenation, acetic acid decomposition, from CO and H2 ethylene and so on. The Pt-Al catalyst containing SC2O3 is used as an important catalyst in the hydrogenation purification and refining process of heavy oil in the petrochemical industry.
Nuclear power industry
Adding a small amount of SC2O3 to UO2 in high-temperature reactor nuclear fuel can avoid lattice transition, volume increase and crack caused by UO2 to U3O8 conversion.
A fuel cell
Similarly, the addition of 2.5%~25% scandium in the nickel base battery will increase the service life.
Agricultural breeding
In agriculture, corn, beet, pea, wheat, sunflower and other seeds can be treated with scandium sulfate (the concentration is generally 10-3~10-8mol/L, different plants will be different). The actual effect of promoting germination has been achieved. After 8 hours, the dry weight of root and bud is increased by 37% and 78%, respectively, compared with that of seedlings.

Storage Condition of Scandium Metal Sc Metal :
The damp reunion will affect Sc metal dispersion performance and using effects, therefore, scandium metal should be sealed in vacuum packing and stored in a cool and dry room, the scandium metal can not be exposure to air. In addition, the scandium metal should be avoided under stress.

Packing & Shipping of Scandium Metal Sc Metal :
It is packed in double plastic bags inside, which can be filled with argon in a vacuum; it can be vacuumed and filled with argon for protection.

Magnesium Diboride MgB2 Powder CAS 12007-25-9

About Magnesium Diboride MgB2 Powder:
Magnesium diboride is an inorganic compound with the molecular formula MgB2. It is a dark gray, insoluble solid. It is an ionic compound with a hexagonal crystal structure. It is an intercalated compound with alternating layers of magnesium and boron. This compound is of interest because it is superconducting at 39 K(−234°C).In terms of composition, MgB2 is markedly different from most transition-metal-based cryogenic superconductors.

Magnesium diboride has been known to scientists for nearly 50 years, but no one has ever studied the material’s superconductivity — whether it can conduct electricity perfectly without resistance when cooled to temperatures close to absolute zero. All that changed in January 2001, when Jun Akimitsu of Aoyama Gakuin University in Tokyo announced that he and his team had found that magnesium diboride became superconducting at 39 degrees Kelvin (-389 degrees Fahrenheit), almost twice the temperature of current intermetallic conductors. The announcement sent experimenters around the world scrambling to replicate and confirm the Japanese findings.

Magnesium boride is converted into a superconductor at a temperature slightly close to the absolute temperature of 40K (-233 ° C). Its transition temperature is nearly twice as high as that of other superconductors of the same type, and its actual operating temperature is between 20 and 30K. This temperature can be achieved by liquid neon, liquid hydrogen, or a closed cycle freezer. These methods are simpler and cheaper than the industry’s use of liquid helium to cool niobium alloys (4K). Once doped with carbon or other impurities, magnesium boride is as good at maintaining superconductivity in the presence of a magnetic field or a current as niobium, or better. Feel free to send an inquiry to get the latest price if you would like to buy Magnesium Diboride MgB2 Powder in bulk.

Magnesium diboride is an ionic compound, with the hexagonal crystal structure. Magnesium diboride at absolute temperature slightly 40K (equivalent to -233 ℃) will be transformed into a superconductor. And its actual operating temperature is 20 ~ 30K. To reach this temperature, we can use liquid neon, liquid hydrogen or closed-cycle refrigerator to finish cooling. Compared to current industry using liquid helium to cool the niobium alloy (4K), these methods are more simple and economical. Once it is doped with carbon or other impurities, magnesium diboride in a magnetic field, or there is a current passing, the ability to maintain the superconducting is as much as niobium alloys, or even better. 
 

How is Magnesium Diboride MgB2 Powder produced?
The preparation method of MgB2 is mainly the reaction synthesis of magnesium powder and boron powder mixed.
MgB2 was obtained by mixing 99.9% magnesium powder with 99% amorphous boron powder at the ratio of 1:2, pressing it into small balls and adding heat in high-pressure nitrogen.

At present, the commonly used method is to mix amorphous elemental boron powder and magnesium powder according to the stoichiometric ratio (or add excessive magnesium), and then put them into a sealed refractory metal container (such as tantalum), and then put them in a quartz tube for vacuum pumping, and then sintered at 700~950for 1~4 h to synthesize MgB2.

Applications of Magnesium Diboride MgB2 Powder:
Potential applications for Magnesium diboride include superconducting magnets, power transmission lines and sensitive magnetic field detectors.

Magnesium diboride is the attention of new materials, the research mainly focused on the synthesis and superconducting element performance for the industrial synthesis and sintering properties, electrical conductivity at room temperature, the liquid aluminum erosion resistance of fluoride such as corrosive resistance study is less, so far no will MgB2 and its composite materials used in aluminum electrolysis cathodic area coverage.

MgB2 is easier to be sintered and densified than TiB2, and its electrical conductivity basically meets the requirements of aluminum electrolysis cathode. Therefore, MgB2 and its composite materials are likely to be widely used as cathode materials for aluminum electrolysis.

Propellants, Explosives, pyrotechnics: Unlike the element boron, which burns incompletely through glass oxide layers that block oxygen diffusion, magnesium diboride burns completely in oxygen or oxidizer mixtures. Therefore, magnesium boride has been proposed as fuel for ramjet jets. In addition, the use of MgB2 in enhanced explosives and propellants has been proposed for the same reason.

Tungsten Boride WB2 Powder CAS 12007-09-9

About Tungsten Boride WB2:
Tungsten borides are compounds of tungsten and boron. Their most remarkable property is high hardness. The Vickers hardness of WB or WB2 crystals is ~20 GPa and that of WB4 is ~30 GPa for loads exceeding 3N.
The relative density of tungsten boride is 10.77 and the melting point is about 2900°C. It does not degrade water and can degrade aqua regia.
It is prepared by heating boron and tungsten powder to a high temperature.
Tungsten boride has comprehensive properties such as high melting point, high hardness and chemical stability. It is only a new superhard material with a high melting point. It is an important military bulletproof material.
For more than 50 years, it has been considered that the rich phase diagram of tungsten alloys, the structure of different phases is also ever-changing.
The highest boride is WB4, which has a three-dimensional grid structure of boron atoms. We put the first the principle calculation is combined with the thermodynamic stability, and the thermodynamic stability and mechanical properties of the possible structure of the tungsten carbide system are systematically studied:
The highest boride to identify tungsten should be WB3 composed of two-dimensional plane boron atoms, not WB4 composed of three-dimensional boron atom grids. It was found that the shear modulus in the borate system of tungsten transformed its formation energy. Increase, revealing that the mechanical properties are closely related to their thermodynamic stability.
Due to the free diffusion coefficient of WB2, the total synthesis of dense tungsten diboride is mostly achieved by sintering technology under high temperature and high-pressure conditions. In this way, it is reduced and the cost is too high; instead, because B will volatilize at high temperature.
Therefore, it is difficult to grasp the content of boron to prepare WB2 bulk materials directly from tungsten powder and boron powder.
It may also generate hypoborate during the sintering process, and compact bulk material with WB2 as the main phase cannot be obtained. Feel free to send an inquiry to get the latest price if you would like to buy Tungsten Boride WB2 powder in bulk.

How is Tungsten Boride WB2 produced?
1. Using metal tungsten and boron as raw materials, fully mix and grind the two, heat and react at above 1400 ℃ to obtain tungsten boride, continue to react to form W2B, and then cool and crush to obtain the product.
2. Tungsten is mixed with stoichiometric boron powder at a molar ratio of W: B=2:1 and sintered in a vacuum or argon atmosphere at 1200 to 1300°C to obtain two tungsten boride.
3. Use the solid phase method. Tungsten boride is prepared from metal tungsten and boron. The reaction formula is as follows. The stoichiometric metal tungsten powder and elemental boron are fully mixed, ground, and molded, and heated and reacted at a temperature above 1400°C to obtain tungsten boride. Continue the reaction to generate W2B, which is cooled and crushed to obtain the product.
