Zircon sand, also known as zirconium sand, zirconium quartz, is a kind of silicate zirconium (ZrSiO4) as the main composition of minerals. Pure zircon sand is colorless transparent crystal, often producing area different, the amount and type of impurities and dyed yellow, orange, red, brown wait for color, crystal structure belongs to tetragonal crystal system, the quartet cone column, the proportion of 4.6 ~ 4.71, the proportion of the changes related to the composition and altered state, sometimes even mohs hardness of 7 ~ 8, the refractive index of 1.93-2.01, The melting point fluctuates with the impurity in 2190~2420ºC. The main chemical composition is ZrO2; SiO2, and a small amount of Fe2O3, CaO, AI2O3 and other impurities.
Zirconia sand is also an indispensable material in the casting field. It is used in refractory materials, casting sand in the casting industry (precision casting sand), precision enamel appliances, and is also used in the production of glass, metal (zirconium sponge) and zirconium compounds.
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.
