Silicates and water glasses in the Donauchem portfolio

Donauchem provides an overview of the silicates and water glasses we offer for technical applications.

General information

Water glasses" are glassy, i.e. amorphous, water-soluble sodium, potassium and lithium silicates or their aqueous solutions, which are formed from a melt and subsequently solidify. Depending on whether the predominant part comes from sodium, potassium or lithium silicate, one speaks of sodium water glass, potassium water glass or lithium water glass.

The drying of the aqueous solution of water glass begins with the evaporation of water, whereby water-insoluble silica is gradually formed (silicification). The silicification of water glass is not reversible, silicic acid and water together do not form the respective water glass again.
