PQ’s silica products consist of highly porous silica gels and precipitated silicas with tight particle size control, ideally suited to surface coating applications, including paints, lacquers, plastics, and paper products.

Silica gels and precipitated silicas are a form of silicon dioxide, the same compound that occurs in nature as sand. However, sand is a crystalline, non-porous form of silicon dioxide, whereas silica gels and precipitated silicas are amorphous (non-crystalline) and highly porous. By carefully controlling surface area, pore volume, particle size distribution, impurities, coatings, and other key characteristics, we can make a range of products optimized for different end uses.
