General Description:  

See also - Silicon Carbide. Hot Pressed Silicon Carbide is a high density, high strength material which has been used in refractory applications for many years. It is now used for a wide range of engineering applications. Silicon Carbide can be highly polished and has potential for space-based mirrors, because of its high specific strength and stiffness compared with those of glass.
