Products Description
Silicon metal 441 is a metallic silicon alloy, which belongs to one kind of industrial silicon. It is mainly composed of silicon and contains some impurities such as iron, aluminum and calcium. Among them, the number "441" represents the specific index of impurity content in the alloy, specifically, the iron content is less than or equal to 0.4%, the aluminum content is less than or equal to 0.4%, and the calcium content is less than or equal to 0.1%.
Silicon metal 441 belongs to crystalline silicon, which is stable and inactive and does not belong to dangerous goods. It is a product smelted by Shi Ying and coke in an electric furnace, and the content of silicon as the main component is about 98%. However, it should be noted that when the particle size of metallic silicon powder is fine to a certain extent (below 5 microns), there may be a risk of explosion under certain conditions.
Silicon metal 441 is an important metallic silicon alloy, which is widely used. For example, silicon metal 441 can improve the corrosion resistance and thermal stability of stainless steel, so it plays an important role in the manufacture of stainless steel. Silicon metal 441 can improve the high-temperature resistance, wear resistance and oxidation resistance of products, so it is also widely used in refractories and powder metallurgy industries. In addition, in terms of electronic materials, Silicon metal 441 is drawn to form monocrystalline silicon, and the processed silicon wafer is widely used in high-tech fields and is an essential raw material for integrated circuits and electronic components.
Generally speaking, silicon metal 441 has important applications in stainless steel manufacturing, high-temperature resistant alloys, metallurgical casting, electronic materials, refractories, powder metallurgy and the silicone chemical industry. Its unique physical and chemical properties make it one of the indispensable materials in these fields.
