Black silicon carbide, also named black carborundum, is made of
quality silicon sand (SiO2) and petroleum coke smelted in high
temperature electric arc furnace. It is black crystal structure
with high hardness, strong cutting ability, stable chemical
characteristics and good thermal conductivity. Its hardness is
higher than corundum, and ranks below diamond and its mechanical
strength is higher than corundum.
Compared with green silicon carbide, its purity, hardness and
brittleness are a little lower than green silicon carbide.
Features of Black Silicon Carbide
◆ Stable chemical characteristics(very low chemical activity)；
◆ Excellent performance of thermal conductivity;
◆ Small thermal expansion coefficient;
◆ Super performance of wear-resisting;
◆ Light weight and high hardness (Moh's hardness:9.2);
◆ Super deoxidizing agent;
◆ High oxidation resistance under high temperature.
