Microsilica (silica fume) is a byproduct from silicon metal or ferrosilicon industries,is an amorphous silicon dioxide â?? SiO2 which is generated as a gas in submerged electrical arc furnaces during the reduction of very pure quartz. As the molten metal is produced, a silica-based gas is emitted. This gaseous fume, as it rises, cools rapidly and forms extremely minute,Amorphous, spherical particles. The microsilica is collected in a bag house, a system for filtering the hot air and gases vented from the furnace. This gas vapor is condensed in bag house collectors as very fine powder of spherical particles that average 0.1 to 0.3 microns in diameter with a surface area of 17 to 30 m2/g. Microsilica can be used in concrete and refractory materials. Microsilica ,when used in concrete, it can improve concreteâ??s properties such as compressive strength, bond strength and abrasion resistance, reduces permeability,and therefore helps in protecting reinforcing steel from corrosion. At the same time, Microslica can still be used in the procustion of refractory and porcelain, to raise intensity and durability, it also can be used in paint, coating resin rubber and other high molecular as a filler material to improve the material overall performance.
Silica sand /Quartz sand is processed by crushing quartz grains of quartz, quartz stone is a kind of non-metallic minerals, is a hard, wear-resistant and stable chemical properties of silicate minerals, the main mineral component is SiO2, quartz sand the color is white or colorless, translucent, Mohs hardness of 7, quartz sand is an important industrial mineral raw materials, non-hazardous chemicals, widely used in glass, foundry, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, abrasive, media and other industries.
Quartz sand is the quartz writing processing of silica particles. Also known as silica, quartz, quartz rock) is a texture hard, wearresisting, stable chemical properties of silicate minerals. In nature exist in quartz sandstone, quartzite and vein quartz. Quartz sandstone is consolidation of clastic rocks, quartz particles content more than 95%,From all kinds of magmatic rocks, sedimentary rocks and metamorphic rocks, heavy minerals is less, associated minerals as feldspar, mica and clay minerals content.Quartzite sedimentary origin and metamorphism, the boundaries of the former clastic particles and cement is not obvious, which is a deep metamorphic grade, quality, and the pure quartz ore.Vein quartz is formed by hydrothermal process, almost all is composed of quartz, dense block structure.
