What role does zircon sand play in the production of glass? Is it a raw material for glass or a production process?
Zircon is mainly an igneous rock formed from magma crystallized zirconium, silicon and oxygen composition of minerals. Zircon is also produced in the dikes and metamorphic rocks. It belongs to the tetragonal system, and is often a well developed cone shaped small tetragonal cylinder, but also irregularly granular. Crisp, broken shell like. It's high quality refractory. With Jin Hongshi, ilmenite, monazite and xenotime in beach sand, and the water, electricity, magnetic separation and other beneficiation process.
First of all, you know what zircon sand is[g o], also known as zirconium sand zircon sand, zircon, is a kind of zirconium silicate (ZrSiO4) as the main mineral composition. Zircon sand pure colorless transparent crystal, often because of quantity and species of different origin and different impurities dyed yellow, orange, red and brown color, crystal structure belongs to tetragonal, a square pyramidal column, the proportion of 4.6 to 4.71, the proportion of the variation with composition and sometimes altered state with zirconium stone incomplete cleavage, uniform Mohs hardness of 7 to 8, the refractive index of 1.93 to 2.01, with the melting point of impurities in different 2190~2420 DEG C wave. The main chemical composition is ZrO2, SiO2, and a small amount of impurities such as Fe2O3, CaO, AI2O3 and so on. The theoretical composition of zircon sand is ZrO2:67.1%; SiO2:32.9%. It is the only compound in the ZrO2-SiO2 system. But natural zircon sand contains only about 57~66%ZrO2.
Zircon sand is the most important zirconium containing mineral, which has the widest distribution, largest reserves and most types in zirconium minerals. It is a kind of mineral with zirconium silicate as the main component. Zircon sand is the main raw material for preparing zirconium, hafnium and many kinds of zirconium products. It has the characteristics of high melting point, low thermal conductivity and small coefficient of linear expansion. It is widely used in metallurgy, casting and other industries.Zircon sand (Gao Yingshi) is highly resistant to heat and has a melting point of 2750. Acid corrosion resistance. 80% of the world's direct use in the foundry industry, ceramics, glass industry, and the manufacture of refractory materials. A small amount used in ferrous alloys, pharmaceuticals, paints, tanning, abrasives, chemicals, and nuclear industries. Very little is used in smelting zirconium metal.
