One, quartz [quartz]

      Quartz is a kind of mineral resources with very stable physical and chemical properties. The chemical formula of quartz is SiO2. The main composition of natural quartz is quartz, which often contains a small amount of impurities such as Al2O3, IMO, CaO, MgO and so on. The appearance of quartz is often white, milky white, gray translucent state, Mohs hardness is 7, the section has glass luster or fat luster, specific gravity varies with the crystal type, varying between 2.22-2.65, its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750℃.

      Silicon powder is a tiny quartz powder particles, generally quartz (silica) content will be very high, more than 99, so called silicon powder. Silicon powder is a kind of inorganic non-metallic material with a wide range of uses. It has excellent dielectric properties, low thermal expansion coefficient and high thermal conductivity. Silicon powder series products are processed from pure quartz powder by advanced ultra-fine grinding process. It has the advantages of high whiteness, fine particles, reasonable particle size distribution, large specific surface area, excellent suspension performance, high purity, Widely used in coatings, paints, adhesives, silicone rubber, precision casting, high-grade ceramics, epoxy resin potting materials and ordinary electrical appliances, high voltage components of the insulation pouring, integrated circuit of plastic and potting materials, powder coating, welding rod protective layer and other resin filler.
