Machining Polished Industrial Silicon Carbide SiC Custom Ceramic Parts
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.
Characteristics:
1.High Hardness
Near diamond-like resistance to abrasion and surface wear.
2.Thermal Stability
Maintains strength at temperatures up to 1,400°C or higher.
3.Thermal Shock Resistance
Withstands rapid temperature swings without cracking due to high thermal conductivity.
4.Chemical Inertness
Resists harsh acids, alkalis, and oxidative environments
