Silicon metal, commonly known as the chemical element silicon, is a hard, gray, corrosion-resistant, high thermal strength metal. It is widely used in many industrial and technological fields. ZHENXIN will detail the main uses of metallic silicon and the industries involved.
1.metal silicon main use：
Silicon metal plays a crucial role in the semiconductor industry. Semiconductors are materials that conduct electricity between conductors and insulators, and silicon is one of the most important elements. The purity of silicon metal directly affects the performance of semiconductor, so the purification technology of silicon metal is one of the key technologies in semiconductor manufacturing process.
Ceramics and glass industry
In the ceramic and glass industries, metallic silicon is used as an additive to improve the properties of materials. For example, adding metallic silicon to ceramics can increase the thermal conductivity of the material and improve the high temperature resistance of the ceramic. Adding metallic silicon to glass can change the refractive index of the glass to meet specific optical requirements.
In the steel industry, silicon metal is often used to produce high-strength, corrosion-resistant silicon steel. Silicon steel is an excellent soft magnetic material, widely used in power industry and electronic industry.
Silicone is a silicon-based organic compound with excellent thermal stability, weather resistance, electrical insulation and physiological inertia. Silicon metal can be used as an important raw material of silicone monomer for the production of various high-performance silicone materials.
2.Second, metal silicon application industry：
Electronics and semiconductor industry
In the electronics and semiconductor industries, silicon metal is mainly used to manufacture integrated circuits, microprocessors, transistors, solar cells and other products. These products are widely used in communication, computer, consumer electronics, automotive electronics and other fields. As a semiconductor base material, the quality of metal silicon directly determines the performance and reliability of the final product. Therefore, in order to meet the increasing technical requirements, the production and purification technology of metallic silicon is also constantly developing and improving.
Refractories and ceramics industry
In the refractory and ceramic industry, silicon metal is mainly used for the production of high-purity refractory materials, high-strength ceramics and special glass. These materials are widely used in the production process of steel, non-ferrous metals, glass and other industries. For example, high-purity refractories can be used as lining materials for iron and steel smelting furnaces to improve furnace life and production efficiency; High-strength ceramics can be used to manufacture tools, engine parts, etc., to improve their hardness and wear resistance; Special glass can be used in optics, electronics, architecture and other fields to improve its light transmission, high temperature resistance and chemical stability.
In the steel industry, metal silicon is mainly used to produce silicon steel, especially oriented silicon steel. Oriented silicon steel is a kind of steel with excellent magnetic properties, which is widely used in the manufacture of transformers, motors and other equipment. In addition, metal silicon can also be used to produce stainless steel, tool steel and other special steel, improve its corrosion resistance and wear resistance.
In the silicone industry, metallic silicon is an important raw material for the production of silicone materials. Silicone materials have excellent thermal stability, weather resistance, electrical insulation and physiological inertia, and are widely used in rubber, plastics, coatings, cosmetics, personal health care and other fields. For example, silicone rubber produced from metal silicon can be used to manufacture seals, insulation materials, etc. The special coatings produced with metal silicon as raw material can be applied to anti-corrosion and decoration in aerospace, automobile and other fields. Cosmetics and personal health care products made of metal silicon can improve their moisturizing and health care effects.
In short, silicon metal is an important industrial raw material, in semiconductor, ceramics and glass, steel, silicone and other industries have a wide range of applications. With the continuous development of science and technology, the application of metal silicon in various industries will continue to expand and deepen, and make greater contributions to promoting global scientific and technological progress.
