Ceramdis - Silicon Carbide (SSiC) is the lightest, but also …
Silicon carbide is mostly used in appliions that require high thermal conductivity. Its extreme hardness, resulting extraordinary resistance to wear, and excellent chemical resistance are the distinguishing qualities of this material. It has become an irreplaceable cornerstone of chemical process engineering, milling processes and dispersion technology.
The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles. Reaction bonded silicon carbide has excellent wear, impact and chemical resistance. It can be formed into a variety of shapes, including cone and sleeve shapes, as well as more complex engineered pieces designed for equipment involved in mineral processing industry.
