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. | | Uses | 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. | | Uses | As binder (e.g., in carbon electrodes, lead pencils, protective coatings, insoluble pigments); detergent, in glass and ceramics manufacture. | | Production Methods | Potassium silicate is produced commercially by fusing silica with potassium carbonate or potassium hydroxide at high temperatures in furnaces. This reaction yields a glass-like solid that is then dissolved in water under controlled conditions to form liquid potassium silicate solutions of varying concentrations. | | Flammability and Explosibility | Not classified | | Mechanism of action | Strengthens plant cell walls creating a physical barrier against pests and diseases. Triggers plants immune system. Coats leaf surfaces inhibiting fungal spore germination | | Pesticide Type | Insecticide; Fungicide |
