Potassium carbonate (chemical formula: K2CO3), also known as potash, is colorless crystals or white particles in appearance, easily soluble in water, and its solution is strongly alkaline. When the saturated aqueous solution is cooled, the glassy monoclinic hydrate 2K2CO3·3H2O crystallizes with a density of 2.043, and the crystal water is lost at 100ºC. Insoluble in ethanol, acetone and ether. Strong hygroscopicity, can absorb carbon dioxide and moisture when exposed to air, and convert it into potassium bicarbonate. It can be obtained by reacting potassium hydroxide with carbon dioxide. It can also be obtained by co-heating potassium chloride with magnesium carbonate, water and carbon dioxide under pressure, or soaking tung seed ash and plant ash.
Application:
1. Potassium carbonate can be used to produce optical glass, which can improve the transparency, strength and refractive index of glass.
2. It is also used to produce welding electrodes, which can prevent arc breaking during welding.
3. It is used to produce vat dyes and their dyeing and ice dyeing.
4. Used as an adsorbent for removing hydrogen sulfide and carbon dioxide.
5. Potassium carbonate mixed with soda ash can be used as dry powder fire extinguishing agent.
6. It can also be used as an auxiliary raw material for acetone and alcohol production and an antioxidant in rubber production.
7. Potassium carbonate aqueous solution can be used for scouring cotton cloth and degreasing wool.
8. It is also used in the production of printing ink, polyester, medicine, electroplating, tanning, ceramics, building materials, crystals and potassium soap.
9. Heavy potassium carbonate is mainly used as the raw material of CRT glass shell, widely used in glass and special glass raw materials, and used for decarbonization of large chemical fertilizer.
10. It can be used as leavening agent in food.
11. It can be used as an alkaline agent and dough improver, and can inhibit the sourness of noodles. It can be used for flour food, and it can be used appropriately according to production needs.
12. Used for the processing of exposed photosensitive materials.
13. Fluxes for analytical reagents, reference reagents and molten silicates and insoluble sulfates.
