Sodium Silicate Uses In Ceramics

Sodium silicate this can be found at most ceramic supply stores and online.
Sodium silicate uses in ceramics. Sodium silicate is commonly used in ceramics as a deflocculant in slip preparation by neutralizing the charges of particles in the slip allowing for more even suspension and thinning. Clay i used about 5 lbs of cone 10 sleeper porcelain for this demo. Because sodium silicate is sticky and dries hard it can be used as a glue to bind ceramic particles together even aggregates. The liquid form of sodium silicate finds many applications such as iron deflocculant in wastewater treatment plants glass manufacturing fire protection detergent auxiliaries cement formulation drilling fluids textile processing desiccant production of silica gel and manufacture of refractory ceramics.
Mixtures of sodium silicate and perlite for example can be rammed into molds to form shapes that dry with zero shrinkage and have excellent. This is a pure sodium silicate solution and should be mixed with water to a 50 50 solution for most casting bodies. Use any clay you like. This is a siccative or drying agent that will harden the layer its applied to causing it dry out and become brittle.
Sodium silicate is a generic name for chemical compounds with the formula na 2x si y o 2y x or na 2 o x sio 2 y such as sodium metasilicate na 2 sio 3 sodium orthosilicate na 4 sio 4 and sodium pyrosilicate na 6 si 2 o 7 the anions are often polymeric these compounds are generally colorless transparent solids or white powders and soluble in water in various amounts.
