Six silicon boride SiB6 powder overview:

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,high specific surface area.The melting point is as high as 2230°C.It is insoluble in water,anti-oxidation,and Chemical corrosion has high 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 and other different sintering The conditions and sealing coil gathering 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,Should 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.

Features 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°C. It is insoluble in water and has anti-oxidant effects, and has high 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.

How is silicon boride SiB6 produced? A method for preparing silicon boride powder is as follows:

A ceramic ball mill is used to uniformly mix silicon powder with an average particle size of less than 1 micron and boron powder with an average particle size of less than 20 microns. The weight ratio of silicon powder and boron powder is 2.85-2.95:7.

After being put into the crucible, put it in a gas protection furnace, pass in argon gas, and heat to 1400-160°C for 50-70 minutes;

At the beginning of the heat preservation, put ASiCl4 into the furnace, 3-5 ml per minute, dripping time 9-11 minutes;

After cooling, the final SIB6 powder product obtained by pulverizing with a ceramic pot ball mill.

Silicon hexaboride SiB6 powder application:

It can be used as a variety of standard abrasives,grinding cemented carbides.It is also used as engineering ceramic materials,sandblasting nozzles,manufacturing gas engine blades and other special-shaped sintered parts and seals.It is used as an antioxidant for refractory materials.
