Microsilicon, also known as silicon powder or microsilicon, is a by-product of the production of silicon metal or ferrosilicon alloys. Silicon metal and alloys are produced in electric furnaces. The raw materials are quartz, coal and wood chips. The fumes from furnace operations are collected and sold as silica fume, which consists primarily of amorphous (non-crystalline) silica (SiO2). ), the average particle size is 0.15~0.20um, the specific surface area is 15000~20000m2/kg, and it has extremely strong surface activity.
1).The appearance is off-white.
2).High resistivity
3).Low penetration rate
4).Excellent resistance to chemical attack by chlorides, acids and sulfates
5).Low chloride ion diffusion
6).Highly active volcanic ash
7).High temperature strength
8).Improve the stability of geothermal environment
1) concrete or shotcrete
• Increase its density and strength, improve its durability,
Impact resistance, corrosion resistance, penetration resistance, frost resistance, etc.
2) Refractory materials and ceramic materials
• Significantly improves its density, strength and high temperature performance.
3) Cement repair products(Mortar and Grout)
• Low permeability, enhanced resistance to chlorides, acids, nitrates and sulfates, etc.
4) Oil well grouting
• Improved durability and compressive strength, reduced permeability, and better control of gas leaks
5) Concrete tiles, roof and wall panels, panels
• Lightweight and improved strength
6) Polymer and rubber products
7) Other applications, such as water glass industry, thermal insulation materials, etc.
