Black Silicon Carbide Powder For Refractory

Silicon Carbide (SiC) powder is a compound made up of silicon and carbon atoms. It has a crystalline structure and is commonly used as an abrasive and refractory material due to its unique properties, such as high hardness, high thermal conductivity, and low thermal expansion.

SiC powder can be produced by several methods, including:

Acheson process: In this process, a mixture of silicon dioxide (SiO2) and carbon is heated to high temperatures in an electric furnace, causing a reaction between the two to form SiC.

Lely process: In this process, SiC is formed by sublimation of a mixture of silicon and carbon at high temperatures, followed by condensation on a cooler surface.

Chemical vapor deposition (CVD): In this process, SiC is deposited onto a substrate by the reaction of a silicon-containing gas (e.g., silane) and a carbon-containing gas (e.g., methane) at high temperatures.
