Zircon sand used for refractory material making
Description
Zircon also known as zircon sand, zircon, is a mineral composed mainly of zirconium silicate. Pure zircon sand is colorless and transparent crystal. It is often dyed yellow, orange, red, brown and other colors due to different origins and different types and quantities of impurities.
Advantages of Zircon
- Wear resistance
- Resistant to heat and vibration
- Good stability
- Strong slag resistance
- Does not stick to molten steel
Application of Zircon
- Ceramics manufacturing
- Refractory material
