High Hardness Silicon Carbide Disc Custom Silicon Carbide Ceramic Plate Round

High Hardness Round SiC Disk Custom Sintered Silicon Carbide Round Plate for High‑Temperature Industrial Application

Silicon Carbide (SiC) is one of the hardest Fine Ceramic materials and exhibits high chemical resistance. In particular, solid-phase sintered silicon carbide is an excellent heat-resistant material that retains its strength even at 1400°C. Moreover, its superior sliding properties make it suitable for applications such as mechanical seals and pump parts, while its high thermal conductivity and electrical semiconductivity render it ideal for semiconductor processing equipment and general industrial machine parts.

Our sintered Silicon Carbide (SiC) ceramic discs are high‑grade advanced ceramic round components manufactured by high‑temperature sintering process. The material delivers outstanding comprehensive performance including ultra‑high hardness, high thermal conductivity, good high‑temperature strength, excellent thermal‑shock resistance and inert chemical stability against most acids and alkalis.

Compared with common alumina ceramics, silicon carbide shows much better heat dissipation and wear‑resisting property, maintaining stable physical performance even under long‑time high‑temperature working environment.

We can supply standard round discs as well as fully customized products: adjustable outer diameter, thickness, flatness, surface roughness. Precision grinding & lapping services are available to meet your strict dimensional and surface quality requirements.
