Carbides and Carbide Materials (hardmetals) Selection

Silicon carbide (SiC) is a compound of silicon metalloid and oxygen. Typically, SiC is used in the alpha silicon carbide structural form. Silicon carbide is a black, high-hardness ceramic that is usually harder than alumina. Depending on the addition of impurities SiC may be green or black in color. Fully-dense SiC can be transparent (moissanite).
