Products Description
Silicon metal is a high-purity silicon material, which usually refers to silicon with a silicon content of more than 99.99%. It is a product which is smelted by Shi Ying and coke in an electric furnace. The content of silicon as the main component is about 98%. In recent years, there are also products with a silicon content of 99.99%. Metal silicon is an important semiconductor material with a gray-black, hard and brittle crystal structure and metallic luster. Its main use is as an additive of non-iron-based alloys, and it is also widely used in energy development, military science and technology, modern communication and other fields.

Silicon metal is an important raw material in the semiconductor industry, especially in the manufacture of integrated circuits, transistors, solar cells and other products. Through a specific doping process, silicon metal can form a semiconductor material with specific conductivity, which provides a foundation for the manufacture of electronic equipment. Silicon metal is an important additive for many alloys, such as aluminum alloy and ferrosilicon alloy. Adding proper amount of silicon metal to the alloy can significantly improve the mechanical properties, corrosion resistance and wear resistance of the alloy, thus optimizing the properties and structure of the alloy.

Silicon metal is the main material for manufacturing solar cells in photovoltaic industry. Through a specific process, silicon metal can be processed into silicon wafers, and then solar panels can be made. These solar panels can convert solar energy into electric energy, which provides important support for the development of clean energy.

Besides, metallic silicon also plays an important role in the fields of architecture, aerospace and so on. As an example, in the field of architecture, metallic silicon can be used as waterproof material, fireproof material, etc. In the aerospace field, metallic silicon can be used to manufacture high-performance composite materials.
