Silicon Carbide Structural Ceramics
Structural ceramics-Silicon Nitride
Structure Ceramics-Si3N4
Structural ceramics is also named engineering ceramics and fine ceramics with excellent wear and corrosion resistance. Combining with electronic ceeramics and functional ceramics,they are called industrial ceramics. Widely used in ceramic valves, sand mill accessories, ceramic seals, dewatering plates, wear-resistant pipe fittings
