Different Purities of SiC Ceramics

2026-09-16
Purity
98–99.5%
Typical applications
Mechanical seals, Wear-resistant parts, furnace components
Industries
Mechanical, chemical, industrial equipment
Purity
99.9–99.99%
Typical applications
Wafer carriers, process tubes, high-temperature components
Industries
Semiconductor, solar, advanced ceramics
Purity
99.999% and above
Typical applications
CVD SiC components, crystal-growth equipment
Industries
Semiconductor, power electronics

Note: Purity is not the only factor. The manufacturing process (RBSiC, SSiC, CVD SiC), density, and free silicon content also affect performance and suitability.
