Audited Supplier Zircon chemical formula: ZrSiO4, also known as zircon, zircon sand. It is a mineral consisting mainly of zirconium, silicon, and oxygen that is crystallized from the magma at the time of the formation of igneous rocks. It is a high quality refractory. The theoretical composition of zircon sand is: ZrO2:67.1%; SiO2:32.9%. Zircon sand is pure colorless and transparent crystal, often because of quantity and species of different origin and different impurities dyed yellow, orange, red and brown color, Mo type hardness of 7.8, the proportion of the refractive index of 1.93-2.01, 4.6-4.71g/cm fand, melting point of 2550 DEG C or above.
Pure zircon sands usually appear as colorless and transparent tetrahedral prismcrystals, because of different origins, the types and quantities of impurities. It is often dyed into yellow, orange, red, brown and other colors.
It usually has a mineral paragenesis with ilmenite, rutile, monazite, xenotime in beach placer, which can be obtained through the water gravity selection, electric separation, magnetic separation and other mineral processing methods, the theoretical components are ZrO2 and SiO2, and small amount of Fe2O3, CaO, Al2O3 and other impurities. In theory, pure zicon sands contains 67.23% and 32.77% SiO2.

Zircon sand used for refractory material (zirconium refractory material, such as corundum brick, zirconium refractory fiber), sand mold casting industry (precision casting sand), precision enamelware, also used in glass, metal (sponge zirconium and zirconium compounds (two) zirconium oxide, zirconium oxychloride, zirconate sodium, etc.) in the production of zirconium sulfate. A small amount of zircon sand is used for iron alloy, medicine, paint, leather, abrasive, chemical and nuclear industry. A very small amount of metal is used to smelt zirconium.
1.The mold coating and the ceramic core used in the mold casting industry. Zircon sand can be used as a quality raw sand for casting, and zircon sand powder is the main component of casting paint. Zircon sand has the characteristics of good thermal conductivity, low and high thermal expansion rate,but compared with other common refractory materials it has high chemical stability, so the quality of zircon and other various adhesives with good adhesion and used in foundry industry.
2.zircon sand is the main material in ceramic industry, also used for glazing, zirconium silicate with high refractive index,
stable chemical performance, widely used in a variety of architectural ceramics, sanitary ceramics, daily-use ceramics, a ceramic crafts such as production, processing the production of ceramic glaze, the use of a wide range of applications, a large amount of. Zirconium silicate is widely used in ceramic production.
3.Zircon sand is a high quality industrial additive. The output of computers and TV sets is increasing rapidly, and the glass
panel with zircon sand is used as an additive to improve its refractive index. Zirconium silicate has also been further applied in the production of emulsion glass, the television industry and in the color picture tube and glass industry.
4.Zircon sand is the main raw material for the preparation of zirconium ZrO2, hafnium and a variety of zirconium products. Zircon sand is also used in glass furnace zircon brick, ladle zircon brick, ramming material, coating and casting material.
5. zircon sand has a special use in many chemical industries, including cosmetics, cement, food corrosion, leather, fiber (used in the manufacture of flame retardant fiber).
