Potassium carbonate, with the chemical formula K2CO3, is an inorganic compound belonging to the carbonate class.<\/p>\n
Appearance: Potassium carbonate is in the form of white crystalline powder, and also in the form of colorless crystalline solid.<\/p>\n
\u200cDensity\u200c: About 2.428g\/cm\u00b3.<\/p>\n
Melting point\u200c: 891\u2103, decomposes at high temperatures.<\/p>\n
\u200cSolubility\u200c: Easily soluble in water, the aqueous solution is alkaline; insoluble in ethanol, acetone and ether.<\/p>\n
\u200cHygroscopicity\u200c: Potassium carbonate has strong hygroscopicity. When exposed to air, it can absorb carbon dioxide and water and turn into potassium bicarbonate, so it should be sealed and packaged.<\/p>\n
Low toxicity, median lethal dose (rat, oral) 1.87g\/kg.<\/p>\n
Irritating.<\/p>\n
Potassium carbonate can react with acid to generate carbon dioxide, and can form precipitation with metal ions.<\/p>\n
In aqueous solution, potassium carbonate will completely ionize potassium ions (K\u207a) and carbonate ions (CO3\u00b2\u207b), making the solution alkaline.<\/p>\n
1. Potassium carbonate can be used to produce optical glass, which can improve the transparency, strength and refractive index of glass.<\/p>\n
2. It is also used to produce welding rods to prevent arc breaking during welding.<\/p>\n
3. It is used to produce vat dyes and their printing and dyeing and ice dyeing.<\/p>\n
4. It is used as an adsorbent to remove hydrogen sulfide and carbon dioxide.<\/p>\n
5. Potassium carbonate can be mixed with soda ash as a dry powder fire extinguishing agent.<\/p>\n
6. It can also be used as an auxiliary raw material for the production of acetone and alcohol and an antioxidant in rubber production.<\/p>\n
7. Potassium carbonate aqueous solution can be used for scouring cotton cloth and degreasing wool.<\/p>\n
8. It is also used in the production of inks, photographic chemicals, polyester, medicine, electroplating, leather, ceramics, building materials, crystal, potassium soap and medicine.<\/p>\n
9. Heavy potassium carbonate is mainly used as a raw material for the glass shell of cathode ray tubes, widely used in glass and special glass raw materials, and used for decarbonization of large fertilizers.<\/p>\n
10. It can be used as a leavening agent in food.<\/p>\n
11. As an alkaline agent and dough improver, it can inhibit the sourness of noodles and can be used in noodle-made foods. Use in appropriate amounts according to production needs.<\/p>\n
12. Used for the processing of exposed photosensitive materials.<\/p>\n
13. Used as analytical reagents, reference reagents, and fluxing agents for molten silicates and insoluble sulfates.<\/p>\n
