of silicon carbide powder, it usually contains traces of chemicals called ''sintering aids'', which are added to support the sintering process by allowing lower sintering temperatures. This type of silicon carbide is often referred to as ''sintered silicon carbide'', or abbreviated to SSiC. The silicon carbide powder is gained from silicon carbide produced as described in the article silicon carbide.
