Silicates are used as plasticisers in the ceramics industry, particularly in the production of floor and wall tiles.

The complex polyvalent silicate anion interacts with the surface of the clays used causing deflocculation. This allows the preparation of high solids, low viscosity systems which are easily handled and pumped. The high solids contents of these slurries reduce the energy costs invollved in drying the clay prior to final firing in a kiln.
