About Nano Ag Silver powder:
Nano Silver is a metal Silver with a particle size of nanoscale. Is Nano Silver healthy? The size of the nanosilver is mostly about 25 nanometers, which has strong inhibition and killing effect on dozens of pathogenic microorganisms such as Escherichia coli, Neisseria gonorrhoeae and Chlamydia trachomatis, and will not produce drug resistance. Made of nanometer silver and combed cotton fiber, cotton socks have good antibacterial and deodorant effects. Does Nano Silver kill germs? In addition to being able to release silver ions, silver nanoparticles can themselves kill bacteria. Silver nanoparticles can accumulate in the pits that form on the cell wall after they anchor to the cell surface. The accumulated silver nanoparticles can cause cell membrane denaturation.
Does Nano Silver kill good bacteria? Silver nanoparticles play an important role in the field of microelectronics because of their excellent electrical conductivity. Due to the surface effect and quantum size effect, silver nanoparticles also have some special applications, such as surface-enhanced Raman applications and medical applications.
Which is better nano silver or colloidal silver? Colloidal silver cannot be used with other beneficial agents and has a weak effect on the biofilm. Therefore, it does not do a sufficient job protecting enamel and balancing the oral biofilm by reducing acid. Nano Silver can be used at much lower concentrations and can penetrate biofilms with ease.
Nanosilver is a powdered silver elemental, particle size is less than 100nm, generally between 25-50nm. The properties of silver nanoparticles are directly related to their particle size. Studies have found that the smaller the particle size, the stronger the bactericidal performance. 
What are the side effects of nano silver? Silver nanoparticles may be absorbed through the lungs, intestine, and through the skin into circulation and thus may reach such organs as the liver, kidney, spleen, brain, heart and testes. Nanosilver may cause mild eyes and skin irritations. It can also act as a mild skin allergen.
Silver Nanopower/Nanopower is a versatile substance with pharmacological, antimicrobial, conductive and chemical uses. Nanopower is dissolved in a variety of solvents, including water, ethanol and isopropyl alcohol, to produce a convenient suspension. Research continues to reveal new applications for silver nanoparticles in areas such as biotechnology, medicine, electronics and manufacturing, where they often achieve the same end result as more expensive solutions.

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.

Technical Parameter of Scandium Metal Sc Metal :

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.
