Silicon Carbide Silicon Carbide (SiC) has good high temperature strength and thermal shock resistance, and is also highly wear resistant. There are two main methods for SiC production, sintering and reaction bonded. Sintered SiC is produced from pure SiC powder with non-oxide sintering aids. Conventional ceramic forming processes are used and the material is sintered in an inert atmosphere at temperatures up to 2000°C or higher. Reaction bonded SiC is made by infiltrating compacts made of mixtures of SiC and Carbon with liquid Silicon. The Silicon reacts with the Carbon forming SiC. The reaction product bonds the SiC particles. Microwave sintering of SiC has been demonstrated at Ceralink. SiC also used extensively as a microwave susceptors because SiC couples with microwave energy directly from room temperature and radiates the heat. Major uses of Silicon Carbide: turbine components, kiln furniture, seals, bearings, wear plates, pump vanes, heat exchangers, ball valve parts, semiconductor wafer processing equipment Material: Ceramic |
