Potassium carbonate, white crystalline powder, soluble in water, aqueous solution is alkaline, insoluble in ethanol, acetone and ether. It is highly hygroscopic. It can absorb carbon dioxide and water when exposed to air. It should be converted into potassium bicarbonate and should be sealed. The hydrate has a water, a dihydrate, and a trihydrate. The aqueous potassium carbonate solution is alkaline and insoluble in ethanol and ether.

The inorganic industry is used to produce sodium potassium tartrate, potassium aluminum fluoride, potassium thiocyanate, and titanium dioxide. The pharmaceutical industry is used to manufacture long-acting sulfonamides, progesterone, cortisone, chlorhexidine, and estradiol benzoate. The glassware industry is used for the preparation of tantalum powder to enhance its leveling properties, to add flux to the glass, and to increase the transparency and refractive index of the glass. The dye industry is used to manufacture indanthine forest, disperse red 3B, reduced ash M, and the like. The printing and dyeing industry is used for the printing and dyeing of vat dyes and the whitening of ice dyes. The rubber industry is used to make 4010 anti-aging agents. The woolen cotton industry is used for cotton scouring and wool degreasing.
Potassium carbonate is one of the important basic inorganic chemicals, medicines and light industrial materials. It is mainly used in optical glass, welding electrodes, electronic tubes, television picture tubes, light bulbs, printing and dyeing, dyes, inks, photographic drugs, sodium silicate, polyester, explosives. , electroplating, tanning, ceramics, building materials, crystal, potassium soap and pharmaceutical production. Used as a gas adsorbent, dry powder fire extinguishing agent, rubber anti-aging agent. Also used to remove carbon dioxide from chemical fertilizer synthesis gas. Can also be used as a potassium-containing fertilizer. With the continuous development of high technology, the application of potassium carbonate in detergent additives, MSG, food and other fields is also expanding.
Potassium carbonate is mainly used in the manufacture of potassium glass, potassium soap and other inorganic chemicals, as well as in the removal of hydrogen sulfide and carbon dioxide from industrial gases, as well as in the field of welding electrodes, ink manufacturing, printing and dyeing industries.
