Potassium silicate(Cat.No:M050517) is a source of highly soluble potassium and silicon. It 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.
