Quartz powder is a hard, wear-resistant, chemically stable silicate mineral, also known as silica micropowder. Its main mineral composition is SiO2, quartz powder is milky white, or colorless and translucent, with hardness of 7 and density of 2.65. Its chemical, thermal and mechanical properties have obvious anisotropy. It is insoluble in acid, slightly soluble in KOH solution, and has a melting point of 1650°C.
Classification of quartz powder
In industry, quartz powder is often divided into: ordinary quartz powder, refined quartz powder, high purity quartz powder, fused quartz powder and silica micronized powder, etc.
Applications of quartz powder
Quartz powder is not divided into grades, but only into specifications. Because it has the characteristics of high whiteness, no impurities, low iron, etc., it has a wide range of applications.
Glass: flat glass, float glass, glass products (glass jars, glass bottles, glass tubes, etc.), optical glass, glass fiber, glass instruments, conductive glass, glass cloth and the main raw material for anti-radiation special glass, etc.
Ceramics and refractory materials: embryo and glaze for porcelain, raw materials for high-silica bricks, ordinary silica bricks and silicon carbide for kilns, etc.
Construction: concrete, cementitious materials, road building materials, artificial marble, cement physical properties test materials, etc.
Electronics: High-purity silicon metal, optical fiber for communication, etc.
