description of metallic silicon powder
Metal silicon powder refers to a kind of fine powder made of high-purity metal silicon through certain smelting, crushing and other processing technologies. Metal silicon powder is gray fine powder with good chemical stability and electrical conductivity.
Second, the application field of metallic silicon powder
1. Building materials field
Metal silicon powder can be added to buildings, cement and concrete, which can significantly improve their strength and crack resistance. At the same time, metal silicon powder can also diffuse into the small pores in concrete to prevent moisture infiltration and improve the durability of concrete.
2. Electronic field
Metal silicon powder is also one of the important raw materials for manufacturing electronic components, such as metal silicon semiconductor materials and metal silicon piezoresistors. After being processed into thin sheets, metal silicon powder can also be used to manufacture solar panels.
3. Metallurgical field
Metal silicon powder is also widely used in metallurgical field. Adding a proper amount of metallic silicon powder can improve the quality of steel and reduce the production cost.
uses of metallic silicon powder
High-purity metallic silicon powder is a kind of high-purity silicon powder, which is mainly composed of metallic silicon and has many important applications. Its main uses are as follows:
1. Preparation of crystalline silicon: High-purity metallic silicon powder is an important raw material for preparing crystalline silicon. Crystalline silicon is widely used in photovoltaic, semiconductor, integrated circuit and other fields, and is an important part of solar panels and electronic devices. As the raw material of crystalline silicon, high-purity metallic silicon powder can improve the purity and quality of crystalline silicon.
2. Alloy preparation: High-purity metallic silicon powder can be used to prepare various alloys. After alloying with other metals (such as aluminum, iron, copper, etc.), metallic silicon has excellent properties, such as high temperature resistance, corrosion resistance and excellent mechanical properties. This metal silicon alloy is widely used in automobile, aerospace, electric power and other industries to improve the performance and service life of materials.
3. Chemical application: High-purity metallic silicon powder can be used as a catalyst or raw material for some chemical reactions. The chemical activity of metallic silicon makes it play an important role in organic synthesis, catalyst preparation and hydrogen production by hydrogenation. In addition, high-purity metallic silicon powder can also be used to produce high-purity silane and organosilicon compounds, which are widely used in silicone rubber, renewable energy, medicine and other fields.
4. Financial application: High-purity metallic silicon powder also has certain applications in the financial industry. Due to the scarcity and importance of metallic silicon, some financial products (such as silicon futures, silicon-based index, etc.) take metallic silicon as the transaction target. As one of the main delivery varieties of silicon futures, high-purity metallic silicon powder has a stable and reliable supply.
