Silica Fume By Flyup Material Resource Corporation

How is Silica fume Produced? Silica fume is by product of producing silicon metal or ferrosilicon alloys in smelters using electric arc furnaces. These metals are used in many industrial applications to include aluminum and steel production, computer chip fabrication, and production of silicones, which are widely used in lubricants and sealants. While these are very valuable materials, the by-product microsilica/silica fume is of more importance to the concrete industry.
