Briefly describe the application of Si Metal Powder - Knowledge

Briefly describe the application of metal silicon powder
1. Deoxidation: Metal silicon powder contains a certain amount of silicon element, which can react with oxygen to produce silicon dioxide, and reduce the reaction capacity during smelting while deoxidizing, making deoxidation safer!
2. Application in the silicone industry: Metal silicon powder can participate in the synthesis of silicone polymers, and can produce high-quality silicon monomers, silicone rubber, silicone oil and other products through metal silicon powder!
3. High temperature resistance: Metal silicon powder can be used in the production of refractory materials and powder metallurgy industries. Adding metal silicon powder during smelting can quickly improve the high temperature resistance of the product, which is usually required by the steelmaking industry!
4. Wear resistance: In the production of some wear-resistant castings, adding metal silicon powder also has a certain application to improve the wear resistance of castings. The use of metal silicon powder can effectively improve the life and quality of castings!
5. Application in the metallurgical casting industry: Metal silicon powder has also been widely used in the metallurgical casting industry. When adding metal silicon powder in steelmaking, it can be used as a deoxidizer, alloy additive, etc., and the effect is good. At the same time, metal silicon powder can also be used as an inoculant in the production of castings.
