KEY FEATURES

  • High Temperature Resistance – With a melting point of 2600°C, SiC maintains strength and stability in extreme furnace conditions.

  • Superior Chemical Stability – Effectively resists attack from molten metal and slag.

  • Outstanding Mechanical Strength – Maintains structural integrity under high load and thermal cycling.

  • Thermal Shock Resistance – Ensures longer service life and reduced downtime.

APPLICATIONS

  • Refractory Bricks – Blast furnaces, cupolas, kilns, and high-temperature reactors

  • Castables & Monolithic Refractories – Tap-hole clay, ladle and furnace linings

  • Continuous Casting – Enhanced erosion resistance and thermal conductivity

  • High-Performance Refractory Mixes – Improved density, reduced porosity, extended service life
