Quality Wholesale refractory material zircon sand  

Zircon sand Description  Zircon sand, also known as zircon sand and zircon, is a mineral composed mainly of zirconium silicate (ZrSiO4). Pure zircon sand is a colorless transparent crystal. It is often dyed yellow, orange, red, brown, etc. due to different origins and different types and types of impurities. The crystal structure is tetragonal and has a quadrangular pyramid shape.The main chemical composition is ZrO2; SiO2, and a small amount of Fe2O3, CaO, AI2O3 and other impurities.The melting point fluctuates with the impurity in 2190~2420ºC.
