Silicon Metal 551

 Silicon metal has the characteristics of high conductivity, high temperature resistance, good chemical stability, excellent mechanical properties, magnetic stability, excellent optical properties, good Biocompatibility and high reproducibility.

Metal silicon smelting demand increases, metal silicon is widely used in daily and industrial production. Prior to the 1990s, the focus was on rare metals, Non-ferrous metal, coal and building materials. With the development of industry and science and technology, semiconductor, solar energy, synthetic metals and other materials are widely used, making the demand for industrial silicon gradually rise, in particular, silicon-aluminum alloy, concrete, fire-resistant materials and hard glass processing used outside silicon demand is huge!

Silicon ore is the most important raw material for industrial silicon smelting, and is also the general name for vein quartz, quartzite and quartz sandstone. Pure silica can be made into quartz glass or refined single crystal silicon. The appearance of crystalline silica is generally milky white, off-white, light yellow and reddish brown. It has a distinct luster, a smooth and continuous cross-section with sharp edges and corners, and is very hard and strong. Vein quartz is in the shape of dense blocks, pure white, translucent, with a grease luster, and a shell-shaped cross section. Most of the quartz crystal particles are more than 2 mm, which can be distinguished by the naked eye. Quartz sand mainly refers to river sand, sea sand, weathered sand, etc. that contain more silica. In addition to the main component silica, it also contains iron oxide, clay, mica and organic impurities. Quartz sand can be divided into quartz sand, quartz powder, ultrafine silica powder, cristobalite, high-purity quartz, etc. according to the grade of the ore body and the degree of processing.
