What is the use of potassium carbonate?

1, potassium carbonate is white crystalline powder, soluble in water, alkaline in aqueous solution, insoluble in ethanol, acetone and ether. Strong hygroscopicity, it can absorb carbon dioxide and water when it meets air and convert it into potassium bicarbonate. 2. Potassium carbonate can be used to prepare glass, printing and dyeing, soap, enamel, potassium salt and decarbonylation of synthetic ammonia, and can also be used in color TV industry, mainly as an expansion agent in food. Mainly used for analytical reagents. Such as high purity analysis, emission spectrum analysis, etc. It can also be used as a flux for silicate and insoluble sulfate, a water absorbent for organic liquid, electroplating, chemical fertilizer, photography and other industries. 3. Used in the electronics industry to manufacture the glass shell of kinescope, decarburization in fertilizer production, production of potassium salt, analytical reagents, fluxes, preparation of various potassium salts, analytical reagents, reference reagents, molten silicate fluxes and insolubles.
