Description

Zircon sand is extremely resistant to high temperatures and its melting point is 2750 degrees Celsius. And resistant to acid corrosion. 80% of the world is directly used in the foundry industry, ceramics, glass industry and the manufacture of refractory materials. A small amount is used in ferroalloys, pharmaceuticals, paints, tanning, abrasives, chemical and nuclear industries

Advantages of Zircon

  • Wear resistance
  • Resistant to heat and vibration
  • Good stability
  • Strong slag resistance
  • Does not stick to molten steel

Application of Zircon

  • Casting/ foundry
  • Refractory fiber manufacturing
  • Zirconium silicate making
  • Glass industry
  • Ceramics manufacturing
  • Refractory material
