Silicon Carbide (SiC) |Ceramic Parts Supply For Over 30 …
Silicon carbide (SiC) features hardness second only to diamond and boron carbide and possesses high wear resistance, thus it''s used for sliding parts (mechanical seals, etc.). In addition, it enjoys a high Young modulus and a small coefficient of thermal expansion, thus it''s used for components (optical parts, substrates, etc.) that require high precision. Because it is a dense sintered body

US Patent Appliion for SILICON CARBIDE SUBSTRATE …
However, when a silicon carbide substrate is cut out from a body of silicon carbide using a wire saw, there was a case where great warpage is generated depending upon the cutting direction. In the case where such a silicon carbide substrate having great warpage is to be ground, attachment to a grinding plate at high accuracy was difficult, and/or the silicon carbide substrate would fall off
