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. Its production started in the 1940s, and, currently, precipitated silica has the greatest commercial importance between the three types of amorphous silica.
Intratec offers professional, easy-to-understand reports examining Precipitated Silica production. Each study describes an industrial plant, including main process units and site infrastructure, and presents an independent analysis of capital and operating costs. All reports are based on the most recent economic data available (2019/20).
