Characteristics and application of silicon boride SiB6 powder

Overview of silicon hexaboride SiB6 powder

Silicon hexaboride is a shiny black-gray powder, molecular formula: SiB6, molecular weight: 92.952 nanometer silicon boride has high purity, small particle size distribution, large specific surface area, melting point up to 2230°C, insoluble in water, resistant to water It has high resistance to oxidation and chemical corrosion, 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, Different sintering conditions and sealing coil aggregation of gas turbine blades 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. Boron SiB6 powder should not be exposed to the air. In addition, avoid using SiB6 powder under pressure.

The SiB6 crystal structure includes interconnected icosahedrons (polyhedrons with 20 faces), icosahedral hexahedrons (polyhedrons with 26 faces), and isolated 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 coefficient of thermal expansion of hexaborides is low, and the nuclear cross section of thermal neutrons is large.

Characteristics of silicon boride SiB6 powder

1. Nano borosilicate has high purity, small particle size distribution and large specific surface area.

2. The melting point is as high as 2230℃. It is insoluble in water, has anti-oxidation effect, and has strong resistance to chemical attack. Especially in terms of high thermal shock and stability;

3. The grinding efficiency of silicon boride is higher than that of boron carbide. It can be used as abrasives, grinding and engineering ceramics, such as nozzles, gas turbine blades and other different sintering conditions and sealing lines.
