Quartz sand As the key raw material of silicon raw material, quartz sand plays an irreplaceable role in the production and supply of silicon raw material, and can be used as tablet glass, float glass, glass products (glass cans, glass bottles, glass tubes, etc.), electronic optical glass, glass chemical fiber, glass equipment, conductive glass Key raw materials for glass cloth and X-ray resistant glass. Fine quartz sand can be used as wear-resistant material for grinding glass, etc.

Quartz sand plays an important role as the main component of glass and raw material for production. Quartz sand is a very stable silicate mineral, which ensures that it is not easy to damage the production process by chemical reaction with other raw materials during glass production. Secondly, quartz sand has high strength and hardness of 7, which increases the firmness of glass and makes glass, glass instruments and equipment more firm; The quartz sand is mostly milky white and translucent, which provides a very convenient standard for the production of various colored plates and colorless glass, and improves the diversity of glass types. It is no longer the same type of glass that was produced only by itself.

Quartz glass is a kind of glass containing only silicon dioxide. Because of different types, processing techniques, and raw materials, they are often called silicate glass, quartz glass, fused quartz, fused quartz, and fused quartz, as well as transparent, translucent, and opaque quartz that have not been defined overseas. In China, quartz glass is commonly called quartz glass, which is classified according to the processing method, main use and appearance, such as transparent quartz glass for electric melting pipe fittings, continuous melting quartz glass, gas refining transparent quartz glass, generated quartz glass, opaque quartz glass, electronic optical quartz glass, quartz glass for semiconductor materials, and quartz glass for energy-saving lamps.

Quartz glass has a series of excellent physical properties, and its linear expansion coefficient is very small, so it can achieve zero expansion theoretically. Quartz glass has excellent light transmission performance, not only through visible light, but also through ultraviolet light and infrared induction. The physical and chemical stability of quartz glass and the excellent performance of electric vacuum pump make it a very good acid resistant raw material, and the continuous high temperature vacuum value can reach 1 × 10-5.

Quartz glass can be used to make semiconductor materials, energy-saving lamps and lanterns, semiconducting communication equipment, laser generators, optical equipment, laboratory equipment, electrical machinery and equipment, medical equipment, heat and corrosion resistant chemical instruments, chemical plants, electronic devices, metallurgical industry, decorative building materials, national defense and safety and other industrial production, and is widely used, High purity quartz glass can also make photoconductive materials
