Silicon Carbide | Ceramic | Sintered | SiC

Silicon carbide probably has the best resistance to corrosion in acids and alkalis of all advanced ceramic materials. It also has extreme hardness and high thermal conductivity and outstanding mechanical properties up to 1400°C. Silicon carbide ceramics have excellent wear resistance and are widely used as mechanical seals.
