Quartz sand is an important industrial raw material that is environmental protection, which is widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasive, filter media and other industries.
Quartz sand mainly has the following applications:
1. Photovoltaic glass: quartz sand is the main raw material of glass industry. The chemical composition and particle size of quartz sand have a decisive influence on its application.
2. Electronics industry: Quartz, as one of the important raw materials in the electronics industry, is widely used in the manufacture of high purity silicon metal, silicon powder, optical fiber, etc.
3. Refractory material: quartz sand has the characteristics of high temperature resistance, small thermal expansion coefficient, can make porcelain embryo and glaze, kiln with high silicon brick, ordinary silicon brick, so that it has fire resistance, high temperature resistance.
4 metallurgical industry: quartz sand as metallurgical industry auxiliary materials, mainly as smelting additives, solvents, silicon metal, ferrosilicon alloy.
5 chemical industry: quartz sand can be used to make sodium silicate and anhydrous silicate, silicon compounds and water glass and other raw materials.
