Si3N4(CERAROI™-N)

  • Electrical Insulation
  • Excellent Strength
  • Support for Complex Shapes

CERAROI™-N has excellent strength, corrosion resistance and fracture toughness, and is widely used for its highly reliable electrical insulation. It supports a wide range of industrial fields because it has little loss of strength up to 1000°C and can cover areas beyond the limits of heat-resistant metals.
