Potassium carbonate, with the chemical formula K2CO3, is an inorganic compound belonging to the carbonate class.
Appearance: Potassium carbonate is in the form of white crystalline powder, and also in the form of colorless crystalline solid.
Density: About 2.428g/cm³.
Melting point: 891℃, decomposes at high temperatures.
Solubility: Easily soluble in water, the aqueous solution is alkaline; insoluble in ethanol, acetone and ether.
Hygroscopicity: 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.
Low toxicity, median lethal dose (rat, oral) 1.87g/kg.
Irritating.
Potassium carbonate can react with acid to generate carbon dioxide, and can form precipitation with metal ions.
In aqueous solution, potassium carbonate will completely ionize potassium ions (K⁺) and carbonate ions (CO3²⁻), making the solution alkaline.
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 rods to prevent arc breaking during welding.
3. It is used to produce vat dyes and their printing and dyeing and ice dyeing.
4. It is used as an adsorbent to remove hydrogen sulfide and carbon dioxide.
5. Potassium carbonate can be mixed with soda ash as a dry powder fire extinguishing agent.
6. It can also be used as an auxiliary raw material for the production of acetone and alcohol 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 inks, photographic chemicals, polyester, medicine, electroplating, leather, ceramics, building materials, crystal, potassium soap and medicine.
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.
10. It can be used as a leavening agent in food.
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.
12. Used for the processing of exposed photosensitive materials.
13. Used as analytical reagents, reference reagents, and fluxing agents for molten silicates and insoluble sulfates.
Keep sealed and dry.
