Microsilica also known as Silica Fume. It's collected and packed from silicon metal or ferrosilicon factories directly, the automatic and integrated production process guarantees the consistent quality. Microsilica are classified as various grades and can be used in Concrete, Oilwell cement, Refractory and Fertilizer industries.
