Precipitated Silica Production Cost Reports | Q4 2019

Precipitated Silica (a.k.a. SiO2) is an amorphous form of silica (silicon dioxide), like silica gel and pyrogenic silica. It is a finely divided white powder, soluble in water, composed of aggregates with up to approximately 1 mm in diameter, generally made by precipitation of an alkaline metal silicate solution.
