1. Manufacturing Process
Category |
Manufacturing Process |
Chemical Vapor Deposition SiC (CVD SiC) |
Silicon carbide material with higher purity, created by the reaction of silicon halides, hydrocarbons, and hydrogen during a decomposition reaction. |
Reaction Bonded SiC |
Silicon carbide products made by mixing SiC powder with a carbon source, followed by heating and a silicon infiltration reaction. |
Recrystallized SiC |
Made from high-purity ultra-fine silicon carbide, it undergoes a process of evaporation, condensation, and recrystallization at temperatures above 2000°C, with particle coalescence at contact points. |
Pressureless Sintered SiC |
Silicon carbide products sintered at temperatures between 2000-2150°C in an atmosphere without applying external pressure. |
Hot Pressed SiC |
Silicon carbide products sintered by applying axial pressure to the body while heating. |
Hot Isostatic Pressed SiC (HIP SiC) |
Silicon carbide products sintered by applying uniform pressure during the heating process to form the final material. |
2. Testing Methods
