Name:zircon sand;
Color: pure zircon sand is a colorless transparent crystal, with different kinds of impurities and different amounts of impurities, dyed yellow, orange, red, brown and other colors;
Granularity: *****0mesh;
Moth hardness:7.5~8;
Chemical formula:ZrSiO4;
Category: silicate;
Proportion:4.**4.8;
Melting point:***0~***0℃;
Main components: mineral deposits of zirconium silicate (ZrSiO4);
Application:
1. Refractories:zirconium corundum brick, zirconium refractory fiber;
2. Casting industry:precision casting molding sand;
3. Ceramic, glass, metal (sponge zirconium) and zirconium compounds (zircon alba, zirconium oxychloride, sodium zirconate, zirconium fluoride potassium, zirconium sulfate, etc.) ferroalloys, pharmaceuticals, paints, tanning, abrasives, chemical and nuclear industries;
4. Smelting metal zirconium.
Product features:
1. Very high temperature resistance, and acid corrosion resistance has high refractoriness, high milk turbidity, high whiteness. The refractive index is high 1.***2.*1, and the chemical properties are stable;
2. The content of ZrO2 is *5 ~ *6% zircon sand because of its resistance to melt (above the melting point of***0℃) and directly used as casting mould material iron metal factory;
3. Zircon sand has low thermal expansion, high thermal conductivity, strong chemical stability and excellent adhesion.
