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.
Zircon sand Application :
1, refractory raw materials: used for the production of zirconium brick, zirconium jade fused brick, sintered brick, water brick, glass kiln zirconium ramming material, castable.
2, ceramics: stable chemical performance, is a kind of high quality, cheap opacification agent, is widely used in all kinds of building ceramics, sanitary ceramics, daily ceramics, first-class handicraft ceramics production, in the processing and production of ceramic glaze, a wide range of use, large dosage.
3, glass: television industry color picture tube, glass industry emulsion glass.
4. Coating: good suspension stability, excellent thixotropy and fluidity, good brushing, brushless coating, low organic content, small gas production, high coating strength.
5, casting: with good thermal conductivity, small thermal expansion, thermal shock stability, high refractoriness, zirconium sand heat storage coefficient is also large. It has a strong cooling effect on castings, which can refine metal structure and improve mechanical properties.
