Silicon hexaboride SiB6 is a shiny black-gray powder, nanometer silicon boride has high purity, small particle size distribution,high specific surface area. It is insoluble in water and resistant to oxidation, thermal shock, and chemical erosion. Especially under thermal shock, it has high strength and stability. The grinding efficiency is higher than boron carbide.

The SiB6 crystal structure contains interconnected icosahedra (polyhedra with 20 faces), icosihexahedra (polyhedra with 26 faces), as well as isolated silicon and boron atoms.

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.
