Canada found that silicon nanoparticles can increase the storage capacity of lithium batteries by 10 times

There are abundant reserves of silicon. Si and Li can be combined to form a Li4.4Si, with a theoretical specific energy of 4200mAh/g. That is almost 10 times more than the lithium ion that is absorbed by today’s lithium batteries. In the present day, silicon materials are used in lithium-ion cells mainly for two reasons. The anode is reconstituted by adding nano-silicon. To improve the performance, organosilicon compounds can be added to the electrolyte.
The University in Alberta created a new generation silicon-based lithium battery

Jillian Biriak and her team at the University of Alberta (Canada) discovered recently that by molding silicon into tiny particles, it can be prevented from breaking.
Nano-silicon can be defined as crystalline particles of silicon that have a diameter less than five nanometers. It is an important nonmetal amorphous substance. Nano silicon powder has high purity and uniformity, as well as a large surface area and high surface activity. It is also non-toxic and smellless. Nano-silicon can have a variety of uses: It can be mixed under high pressure with diamonds to form composite materials that can be cut with, or combined with graphite material to create composite silicon-carbon materials. The negative electrode material in lithium-ion cells increases the battery’s capacity. This material can be combined with organic matter to create organic silicon polymer.

The team studied and tested four sizes of nanoparticles of silicon to determine which size would maximize its advantages while minimizing the disadvantages. They are evenly dispersed in a highly conductive graphene-carbon aerogel with nanopores that compensates for the low conductivity silicon.

After multiple cycles of charge and discharge, they found that particles as small as one part per meter showed the most stability. This eliminates the limitations of using silicon for lithium-ion battery. This discovery could result in batteries that have 10 times the current capacity of lithium-ion battery. It’s a major step toward the manufacture of new lithium-ion lithium batteries based on silicon. The research findings were published in the journal Materials Chemistry.

The lithium battery industry’s chain of tens billions in silicon anode sales

This research can be applied in many fields, including electric vehicles. The batteries will become lighter, travel longer and charge faster. Next step will be to create a method that is faster and cheaper to produce silicon nanoparticles. This will make it easier for industrial production.

Other than new energy vehicles, the need for lithium-ion battery with higher energy and power density is also present in energy storage and shipbuilding. It is now common to use high nickel ternary material as the positive electrode, while silicon or its Composite materials has emerged as the best material for the negative electrode.

Properties of Zirconia and Common Preparation Methods

What is zirconia

Zirconium is a primary oxide with the chemical formula ZrO2. Normal conditions produce a white, odorless crystal. It’s insoluble in hydrochloric and dilute acid, but it’s soluble in distilled water. Chemical properties do not exist. Its properties include high melting points, high resistivity and high refractive indices, as well as low thermal expansion coefficients. This makes it a ceramic sunscreen, ceramic insulating materials and ceramic insulation. It is also used as the primary raw materials for artificial drills.

How to prepare zirconia

1. Chemical Method (Alkali Metal Method)

The zircon concentration powder is added to caustic soap at high temperatures to produce sodium azirconate. The sodium zirconate, washed in concentrated hydrochloric to produce zirconium dioxide (ZH), Cl2, is then dried with a slurry of ammonia water. The zirconium oxide SH2OX is dissolved in water and then ammonia-water is added to precipitate the Zr(OH). You can burn Zr(OH1S), to get zirconia.

It is possible to add hydrochloric, or sulfuric, acid to the precipitate after melting zircon (Na2ZrO3, or Na2SiO3, or undecomposed products) by adding water to leaching. Zr(OH). Leach acid, remove precipitation and then add ammonia-water to prepare Zr (OH). The zircon can also be added to alkaline earth metal carbonates or oxides, then calcined into calcium zirconate. Finally, it is boiled in hydrochloric to remove the impurities and obtain zirconia.

2. Electrofusion method for Zirconia preparation

Reduced desalinization is achieved by melting zircon and reducing its size in an electric furnace. In an electric furnace, at 2700 degrees, zircon is completely decomposed, resulting in liquid ZrO2 or SiO2. At the same time SiO2 can decompose into gaseous siO2 and oxygen, which is a reverse reaction.

Two methods are available for the preparation of stable zirconia using the electric melt method: primary melting and secondary melting. For the primary electric melting method, you need to mix zircon powder with graphite and stabilizers (usually calcite CaCO3). Add them to an electric furnace and melt. After the ZrO2 is fused, it is quenched in order to promote crystallization. In the second electric melting method the zircon powder is mixed with graphite, then melted and quenched in an electric furnace. Then, it is lightly burnt (about 1450degC) until mZrO2 has been obtained. The mZrO2 mixed in the specified proportion is added to an electric arc melting furnace, quenched, and then lightly burned (about 1400degC) to obtain m-ZrO2.

Properties and Applications of Boron Carbide

The crystal lattice of the boron-carbide crystal is D3d5R3m. The rhombohedral lattice can be described as an icosahedron-shaped primitive cell grid that extends diagonally in the space. The c-axis is the same as the diagonal of the area. A linear chain is formed by connecting three boron-atoms to an adjacent icosahedron. Three of the 12 icosahedral position are found on the chain. If B is due to the position of the icosahedron while C is in the linear chain, the stoichiometry is B4C.

1. Basic properties and applications for boron carbide

Low density

B4C density is small at 2.52g/cm3. The empirical formula (9) can be used to express the relationship between carbon content and density in the homogeneous area.

r=2.4224+0.00489C%(9)

Because of the low density of the boron carbide, when the density is increased, the performance of the boron carbide can reach the standard, which means high strength, high toughness, and excellent performance. Therefore, it can be used for lightweight armor in order to reduce the body weight of vehicles and tanks. Save energy.

Hardness and wear resistant

B4C exhibits super hardness, and a high level of wear resistance. B4C’s Vickers Hardness in homogeneous areas increases as the C content increases. The hardness of carbon is 29.1 GPa when carbon is 10.6%. When carbon is 20%, hardness 21 can be as high as 37.7 GPa. At high temperature, its hardness remains high (>30GPa). You can express the change in hardness with temperature by using empirical formula (10).

H=H0-exp(-aT)(10)

The formula is: H0-the hardness of the material at room temperature

Temperature is T.

Carbon is a constant.

This formula applies to 201700. B4C is second only to cubic BN and diamond in terms of hardness.

B4C wear resistance increases with temperature. As the temperature increases, the friction coefficient of B4C decreases. It drops to 0.05 between 20 and 1400, while the friction rate continues to decline. B4C’s super hardness and friction properties have made it a popular nozzle for sandblasting.

What is amorphous boron and its applications?

Amorphous boron Amorphous boron This is a form boron. The elemental boron occurs rarely in nature as its pure form, but as orthoboric or borates. Boron’s energy gap of 1,50 to 1,556 eV is greater than that of silicon or germanium. It transmits parts of infrared. At room temperature, boron is not as good a conductor of electricity. Boron is available in crystalline and amorphous forms. Boron is odorless and tasteless. Amorphous Boron is a brownish powder. Crystalline boron, on the other hand, is black in color and is extremely hard. (roughly 9.5 Mohs’ Scale) It is also a poor conductor when at room temperatures. In the periodic chart of elements, boron lies between the non-metal and metal element series. Boron’s chemical properties are active due to many of its characteristics. These include a strong electronegative charge, low atomic size, and a central nuclear charge. The non-metal of boron is very similar to silicon. At high temperature, boron may react with sulfur, oxygen, nitrogen or halogen. Boron remains stable at room temperature. However, it becomes oxidized and then burns when heated up to 300°C. Boron is easily combined with metals of all kinds to produce metal boride. High purity boron can be crystalline. The vapor phase reaction of boron chloride or tribromide and hydrogen can be used to prepare crystalline boron.

The Characteristics and Application of Quartz Powder

What exactly is quartz powder? It’s also called silicon fine powder. Quartz powder is a hard mineral that is known for its chemical stability and wear resistance. The quartz sand color is white or translucent. Its hardness is 7, it has brittle fractures and an oil gloss. The product of the quartz mine is referred to by the term below 120 mesh. Quartz powder has more than 120 different products as their destination.

What are the uses of quartz powder?
Quartz is the most abundant mineral on earth. Quartz Powder has many uses in industry.

In the glass-making industry, rich quartz sands are used. Quartz sand plays a key role in the production of instrumentation, flat-sheet, specialty, and fiberglass glass. Quartz can also be used to produce lenses for optical instruments such as telescopes, microscopes prisms sensors and electronic and scientific instruments.

Quartz Powder as an Abrasive. Because of its high hardness, which is seven on the Mohs scaling, quartz powder is more durable and effective than many other natural substances. Quartz powders and finely ground oxides have many uses, including sandblasting media, scouring cleanser, grinding media, grit, and sanding for sawing and sanding.

Quartz Powder used in the Slab Industry. Quartz Grains and powder are also used to produce artificial marble and quartz slabs. Since the very beginning, we are producing the best quality for this industry.

Quartz powder is also used in the manufacture of rubber, putty, and paint. The screened and washed grains of quartz are used in roofing granules, as well as for filter media. Quartz Powder is used to provide traction in the mining, railroad and construction industries. These sands can be found on golf course sandboxes and beaches. They are also used for volleyball courts, baseball pitches, children’s sandboxes.

Quantum Powder for Investigation of the Properties of Engineered Cementitious Composites Reinforced by Fibers
ECC mixes are more workable when they contain quartz powder and silica dust. These materials can absorb water. Water absorption is lower for cement and quartz than silica. Silica fume, however, has a specific area of between 15,000-30,000m2/kg. Besides that, all ECC mixtures are always made with water. In essence, these conditions may be the cause of the poor workability of ECC mixes. By adjusting superplasticizer content (SP) for each mix, however, ECC mixes can be made to work well and have good consistency.

In the case of PVA fibers based ECCs, adding quartz powder can improve the average compressive strengths of 6.85% and the average strength ratios of 1.0685 compared with the PVA fibres based samples that do not contain quartz powder. The addition of quartz to steel fibers based ECC can improve the average strength ratio or compressive strength by 8.9% compared with the steel fibres based ECC samples that do not contain quartz powder. The addition of the quartz powder to the steel fibers and PVA ECC samples led to higher compressive strengths with an average strength of 1.0747 when compared to samples of FR ECC without quartz.
