metallurgical brinell hardness of silicon carbide

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.
