Silicon Carbide Ceramics

Silicon Carbide SiC

Silicon Carbide Ceramics are light, high young modulus and high hardness material which has highly potential as structural materials. The ceramics are capable to be used as Abrasion resistance material as well as the materials which is used under high load condition with precised dimension maintenance. Also, the material has some certain level of electrical conductivity, so exhibits electrical static discharge function.
