Usage:
Potassium Carbonate is used as raw materials in manufacturing electro tube, TV kinescope, computer display. It is applied in optical glass improving clarity, strength and refractive index. It is also applied in electrode avoiding electric arc breaking-off during welding. It is used to produce food additives like potassium sorbate, monopotassium phosphate, etc. Potassium Carbonate is foliar spray fertilizer and a constituent of compound fertilizer. In dyeing industry, it is used to produce vat dyestuff and discharge of ice dyeing.
