Potassium silicate

Chemical properties

(Solid) Weight ratio Si O 2 :K 2 O varies with grade from 2.1:1 to 2.5:1; colorless anhydrous lump, shattered or granular. Soluble in water at high temperature and pressure; insoluble in alco- hol. (Solution) Colorless liquid, B′e range 29–48 degrees.

The Uses of Potassium silicate

Potassium silicate is used in binders, carbon electrodes, lead pencils, protective coatings, insoluble pigments, phosphors on television tubes and detergent additives. It acts as a catalyst to make glass, ceramics, welding rods, adhesives, cements, gels, paints, pulp and paper production. Further, it is used in horticulture as a soluble source of potassium and silicon. It acts as a corrosion inhibitor.

The Uses of Potassium silicate

As binder (e.g., in carbon electrodes, lead pencils, protective coatings, insoluble pigments); detergent, in glass and ceramics manufacture.
