PQ Soluble Silicates are vital to the production of numerous high-performance value-added silica-based chemicals in the electronic, catalyst, life science, personal care, food chemical, and automotive markets.  Examples include the use of colloidal silica for silicon wafer polishing, processing in computer electronics and the use of zeolite catalysts in petrochemical refining.  PQ sodium silicates are used by the industry to manufacture these high-value silica chemicals.  PQ’s expertise is integral to producing the high-quality sodium silicates needed for these demanding applications.
How It Works

In the manufacture of silica-based products, liquid sodium silicates  provide a readily available, convenient source of soluble silica. In many cases, the silicate is modified by addition of acid to neutralize the alkalinity of the silicate and release the silica.  Silicates are used to produce these derivative products:  

  • Precipitated silicas
  • Silica gels (adsorbent and chromatography)
  • Colloidal silicas (silica sols) 
  • Catalyst supports (modified silica gels) 
  • Zeolites (sodium aluminosilicates) 
  • Zeolite Catalysts
  • Pigments (TiO2)
