Silicates

Different kinds of colloidal silicates solutions exist in the market. Single oxides and binary alkali silicates of Li, Na and K in both solid and dispersed state.
Alkali silicates are a family of chemicals with a wide range of physical and chemical properties. They are  prepared by fusing sodium or potassium carbonate with sand or by heating sodium or potassium hydroxide with sand under pressure. The various characteristics of  Alkali silicates permit their use in a variety of applications such as : welding rods, soaps, detergents, hard-surface cleaners, coating materials, and electronics. 
These chemicals have been used extensively on the synthesis of low cost silica gels but they need a washing procedure to remove alkalis. They can be used as precursors for multicomponent gels.
