Understanding Our Products

The Chemicals Division of the PQ Corporation manufactures inorganic water-based products based on the chemistry of Silicon, Aluminum, and Magnesium.  Silicon chemistries are sourced from silica sand and include a range of products from Soluble Silicates to Sodium Aluminosilicates (Zeolites) to Silica Gels.  Likewise PQ is the largest North American manufacturer of Magnesium Sulfate Heptahdyrate, also know as Epsom Salt, and related products.  While these PQ products each are very different chemically, the products have a wide range of industrial applications in common. 

To better appreciate how our products are used, it is important to understand some of the basics of their composition and chemistry.
