Silica fume production What is silica fume. Silica fume, also known as microsilica, fumed silica. When smelting ferrosilicon and industrial silicon metal silicon, a large amount of highly volatile SiO2 and Si gas is generated in the ore furnace. And the gas is rapidly oxidized after being discharged.
Silica Fume Properties. Microsilica is a byproduct from the production of silicon metal and alloys. It is produced by condensing the vapours released during the ferrosilicon smelting process. This produces extremely fine particles, as shown in the below diagram.
Product name Silica Fume Microsilica Grade 90 Silica fume, a co-product from the production of silicon or ferrosilicon metal, is an amorphous silicon dioxide - SiO2 which is generated as a gas in submerged electrical arc furnaces during the reduction of very pure quartz.

May 01, 1982 Silica fume, a by-product in the manufacture of ferrosilicon and also of silicon metal, is a very efficient pozzolanic material, though there are some problems associated with its use in concrete. The use of silica fume in concrete should be limited to specialized applications that can take full advantage of its unique properties.
