What are the physical and chemical properties of silicon hexaboride

Silicon boride can be used as various standard abrasives and grinding cemented carbides. It is also used as engineering ceramic materials, sandblasting nozzles, blades of gas engines and other special-shaped sintered parts and seals. Used as an antioxidant for refractory materials.

What are the physical and chemical properties of silicon hexaboride

Glossy black-gray powder, relative density 3.0g/cm3, melting point 2200℃.

It is insoluble in water, resistant to oxidation, thermal shock, and chemical attack, especially with high strength and stability under thermal shock.

The grinding efficiency is higher than that of boron carbide.

Chemical formula: SiB6

How harmful is silicon hexaboride

This product is usually not harmful to water. If there is no government permission, do not discharge the material into the surrounding environment.

Overview of silicon hexaboride SiB6 powder

Silicon hexaboride SiB6 powder is a shiny black-gray powder, molecular formula: SiB6, molecular weight: 92.952 nanometers. Silicon boride has high purity, small particle size distribution, large specific surface area, and melting point as high as 2230°C. Insoluble in water, anti-oxidation, chemical resistance, especially in terms of high thermal shock and stability; silicon boride has a higher grinding efficiency than boron carbide, and can be used as abrasives, grinding and engineering ceramics, such as nozzles, gas turbine blades Different sintering conditions and sealing coil aggregation affect the dispersion performance and use effect of SiB6 powder. Therefore, silicon boride SiB6 powder should be sealed in a vacuum package and stored in a cool and dry room. Silicon boride SiB6 powder should not be exposed to the air. In addition, avoid using SiB6 powder under pressure.

The crystal structure of silicon hexaboride SIB6 consists of interconnected icosahedrons (using 20-sided polyhedrons), icosahedral hexahedrons (26-sided polyhedrons), and separated silicon and boron atoms. Compared with hexaboride, it is metastable. However, since crystal nucleation and growth are relatively easy, they can be prepared.

When heated in air or oxygen, the surface of SiB6 is oxidized and corroded by boiling sulfuric acid and fluorine, chlorine, and bromine at high temperatures. Silicon boride is conductive. The thermal expansion coefficient of hexaboride is low, and the nuclear cross section of thermal neutrons is large.
