96U Undensified Silica Fume

Products, Undensified Silica Fume
When silica fume is used to smelt ferrosilicon and industrial silicon (metal silicon), a lot of strong volatile SiO2 and Si gases are produced in the submerged arc furnace. After the gas is discharged, it contact with air and is rapidly oxidized and condensed. It is a product of large industrial smelting. The whole process needs to be recovered by…

Silica fume, also known as microsilica, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product during silicon and ferrosilicon alloy production. According to the SiO2 content, our products can arrange form grade 85% to grade 96%. According to the bulk density, we can divide our products into densified silica fume and…
