Silicon carbide parts outperform alumina and zirconia ceramics in nearly every aspect where heat, wear, or corrosion resistance is critical. SiC has an exceptionally high thermal conductivity up to 200 W/m·K, higher than alumina and zirconia. This property make it ideal for heat-dissipating components like semiconductor chucks and heater plates. High Mohs hardness up to 9.5 provides longer life and wear resistance. Silicon carbide also has high strength and minimal deformation in high-temperature environment. Excellent thermal shock resistance of SiC provides stability under rapid cycles of heating and cooling. Strong chemical inertness allows SiC parts to resist corrosion.
Overall, silicon carbide offers heat resistance, strength and stability. SiC parts are the better choice in harsh industrial environment, where alumina or zirconia cannot survive.
Yes, but it is very difficult. Due to its extreme hardness and brittleness, silicon carbide can only be machined with diamond tools. Post-processing is limited to precision grinding or polishing, which aims to achieve fine tolerances or mirror finishes. Because this process is costly and slow, most SiC parts are made close to their final dimensions before sintering to minimize later machining.
