Silica Fume Silica Gel Composite Hose Superplasticizer

What is Silica Fume

Silica fume (also known as microsilica) is very fine noncrystalline silica by-product resulting from the reduction of high-purity quartz and carbon in electric arc furnaces during the production of elemental silicon or alloys containing silicon.
