Precipitated silica is a highly versatile and fine white powder produced through a precise precipitation process involving silicate salts. Renowned for its amorphous structure, this form of silicon dioxide (SiO2) is created by inducing a chemical reaction between an alkaline silicate solution and a mineral acid like sulfuric acid. The controlled parameters during production—including agitation, reaction duration, addition rates, temperature, concentration, and pH—allow manufacturers to tailor the physical properties and performance characteristics of the precipitated silica to meet diverse industrial needs. Key benefits of precipitated silica include its high surface area, excellent absorbent capabilities, and unique reinforcing properties, making it an essential ingredient across multiple sectors such as rubber, coatings, and pharmaceuticals. Contrary to gel forms, the manufacturing process prevents the formation of undesirable gel stages, ensuring the final product is a high-quality, dry powder suitable for a broad range of applications.

Precipitated silica is an amorphous form of silica (silicon dioxide, SiO2); it is a white, powdery material. Precipitated silica is produced by precipitation from a solution containing silicate salts. The three main classes of amorphous silica are pyrogenic silica, precipitated silica and silica gel.
