Actually, metallic silica fume has many functions and can be used in many different fields, but because people do not have a comprehensive understanding of metallic silica fume, or some people do not understand metallic silica fume, so the development of metallic silica fume in the market situation is not very good, in order to break this situation, but also to be able to Enough to let more people understand the metal silicon powder, further promote the development of metal silicon powder, will be aimed at the role of metal silicon powder and application areas for a simple explanation.
1, silicon metal can produce silicone rubber, silicone resin, silicone oil and other organic silicon. Silicone rubber produced by metal silicon has good elasticity and high temperature resistance, and is used for making medical supplies, high temperature gaskets and so on. Silicone resin is used to produce insulating varnish, high temperature paint and so on. Silicone oil is an oily substance whose viscosity is little affected by temperature. It is used to produce lubricants, polishers, fluid springs, dielectric liquids, etc. It can also be processed into colorless transparent liquids, which can be sprayed on the surface of buildings as waterproofing agents.
2, manufacturing high purity semiconductors. Modern large-scale integrated circuits are almost all made of high-purity metal silicon, and high-purity metal silicon is still the main raw material for the production of optical fiber, it can be said that metal silicon has become the basic pillar industry in the information age.
3, preparation of alloy. Silicon-aluminium alloy is a kind of strong composite deoxidizer. Replacing pure aluminium in steelmaking process can improve the utilization rate of deoxidizer, purify molten steel and improve the quality of steel. Silicon-aluminium alloy has low density, low coefficient of thermal expansion, good casting performance and wear resistance. Its alloy castings have high impact resistance and high pressure compactness, which can greatly improve service life. It is often used to produce spacecraft and automotive parts.
