4) 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. It is absorbent removing hydrogen
sulfide and carbon dioxide; dry powder extinguisher mixed with soda;
auxiliary raw material for producing alcohol and acetone; and anti-aging
agent in rubber production. Its solution is used in boiling and scouring of
cotton cloth and wool's degreasing. In addition, it is also used in
manufacture of printing ink, photograph-drug, polyester, explosives,
electroplating, tanning, ceramic, building materials, crystals and medicine
