silica fume

タイトルまたは説明

SIMAG’s extensive purchasing chain of silicon metal provides the aspiring enterprise with opportunities to develop the byproducts of silicon industry, such as Silica Fume (microsilica). As the spin-offs from silicon metal and ferro-silicon mills, Silica fume is a high-performance mineral additive widely used in construction and refractories. SIMAG is specialized in both densified and undensified materials, with SiO2 content from *3% to *7%, sourcing from production of silicon metal to ferro-silicon. Packages are flexible from jumbo packs to special portable bags, subject to customers’ preference. Product Introduction: Silica fume (Microsilica) is a mineral composed of ultra-fine amorphous spheres of silicon dioxide (SiO2), produced during the manufacture of silicon or ferrosilicon. Silica fume is formed when SiO gas is oxidised to SiO2, condensing into the pure spherical particles of microsilica, forming the major part of the smoke or fume from the furnace. Rather than being landfilled, the collected smoke is sold as silica fume for various applications.
