A powdery substance made from silicon dioxide as the main raw material and processed in a high-temperature furnace. It has high chemical stability, thermal stability and mechanical strength, so it has a wide range of applications in various industries. It can be used to make high-strength cement and concrete in construction. Adding an appropriate amount of silica fume to concrete can improve the compactness and strength of concrete.
1.Building materials
Silica fume can be used as the main admixture in building materials and has multiple functions such as improving concrete properties and increasing strength. In addition, silica powder can also be used for waterproofing, fireproofing, etc.
2. Chemical industry
Silica powder is widely used in the chemical industry and can be used for filling rubber products, manufacturing silicone rubber, and coating additives. In addition, silica powder can also be used as a catalyst to catalyze alkylation reactions, etc.
3. Electronics
Silicon powder can be used as a raw material for semiconductor materials to prepare various silicon wafers, optical fibers and other electronic components, and is used in electronic communications, computers and other fields.
4.Metallurgy
Raw materials for metallurgical industries such as steel production, ceramic processing, and ferroalloy smelting.
5. Medicine
Silica powder is mostly used in pharmaceutical auxiliaries, medical materials, etc. in the pharmaceutical industry. Silica powder is widely used in the pharmaceutical industry, such as tablet fillers, adhesives, co-solvents, etc.
