Microsilica,also name silica fume.It is a by-product in the manufacturing of ferrosilicon and metallic silicon in high-temperature electric arc furnaces.
it is an amorphous silicondioxide (SiO2) consisting of sub micron spherical primary particles and agglomerates.
Microsilica,also name silica fume, is densified to 300kg/cmb to 700kg/cbm after it collected from electric arc furnaces,and classified according to SiO2 contained, 85%, 88%, 90%, 92%, 94% and 96% etc.
It is packed in jumbo bag in 1000kgs/bag or 700kg/bag,500kgs/per bag,according customer requirement and the bulk density.
