Silicon carbide etched disk and manipulator
Application
1. SiC products mainly include Sintered Silicon Carbide (SSiC), Reaction Sintered Silicon Carbide (RBSC) and Chemical Vapor Deposition Silicon Carbide (CVD SiC).
2. SiC product has various excellent properties:
► Super hardness
► Excellent wear resistance
► High thermal conductivity and mechanical strength
►Low coefficient of thermal expansion
► Excellent thermal stability
► Low density
► Specific stiffness
► Nonmagnetic
3. At present, SiC products are used in aviation, aerospace, nuclear industry and other industries, such as SiC mirrors, ceramic parts for high-end equipment such as integrated circuit manufacturing, heat exchangers under extreme conditions, bulletproof materials, etc.
