Products Description
Silicon metal 441 is also called crystalline silicon or industrial silicon. It is a product made of Shi Ying and coke smelted in an electric furnace. Among them, the content of silicon is about 98%, and the rest impurities are mainly iron, aluminum and calcium. According to the contents of iron, aluminum and calcium in silicon metal . Silicon metal 441 represents 0.4% or less of iron, 0.4% or less of aluminum and 0.1% or less of calcium. Its main use is as an additive for non-iron-based alloys. The international common practice is to divide commercial silicon into metal silicon and semiconductor silicon. Semiconductor silicon is high-purity metallic silicon used to make semiconductor devices. It is sold in polycrystalline and single crystal form, the former is cheap and the latter is expensive.
Silicon metal 441 is famous for its high purity, high crystallinity and excellent thermal stability. These characteristics make it stable in extreme environments such as high temperature and high pressure, so it is widely used in various industries. For example, silicon metal 441 plays an important role in the semiconductor industry. Semiconductor material is the key raw material for manufacturing integrated circuits, solar cells and other products, and metal silicon 441 has excellent conductivity and stability. Therefore, it has become an ideal choice for manufacturing semiconductor devices.
In addition, silicon metal 441 has been widely used in aerospace, automobile manufacturing and other fields. In the aerospace field, the high strength and light weight of silicon metal 441 make it an ideal material for aircraft such as airplanes and rockets. In the field of automobile manufacturing, the high temperature resistance and wear resistance of silicon metal 441 make it a key factor to improve the performance of automobile engines and prolong the service life of automobiles.
