Silicon carbide (SiC) is a compound founded on silicon and carbon, renowned for its mechanical strength, thermal stability, chemical resistance, and wear durability. Due to these attributes, SiC is extensively used in high-temperature, high-wear environments such as furnaces, kilns, chemical plants, and semiconductor processing. Its unique structure enables minimal loss of mechanical integrity even above 1000°C – a key differentiator from competing fine ceramics.
- High thermal conductivity and resistance: Maintains performance up to 1400°C.
- Superior chemical stability: Resistant to acids, alkalis, and corrosive media.
- Mechanical durability: Excellent flexural strength and abrasion resistance.
- Industrial uses: From furnace linings and burner nozzles to semiconductor equipment, mechanical seals, bearings, and pump parts.
Japanese industries are supported by a select group of silicon carbide refractory manufacturers and suppliers that combine tradition, precision engineering, and cutting-edge R&D.
