Product properties & Features

Potassium carbonate (chemical formula: K2CO3, English Potassiumcarbonate), also known as potash, appearance is colorless crystal or white particles, easily soluble in water, its solution is strongly alkaline. When the saturated aqueous solution was cooled, 2K2CO3·3H2O of the glass monoclinic crystal hydrate crystallised out with a density of 2.043, and the crystal water was lost at 100℃. Insoluble in ethanol, acetone and ether. Hygroscopic, exposed to air Chemicalbook can absorb carbon dioxide and water, into potassium bicarbonate. It can be obtained by reacting potassium hydroxide with carbon dioxide. It can also be made of potassium chloride with magnesium carbonate, water and carbon dioxide under pressure, or by impregnating the ash of Tong seed and grass and wood. Mainly used for syngas decarbonization, vacuum tube, glass, enamel, printing and dyeing, welding electrode, film development, inorganic salt and picture tube glass shell raw materials, impurity potassium carbonate common name of oxaline, alutine or pearl ash, one of the early potassium fertilizer varieties.

Application

1. Potassium carbonate can be used to produce optical glass, which can improve the transparency, strength and refractive coefficient of glass. 2. Also used in the production of welding rod, can prevent the phenomenon of arc breaking during welding. 3. Used for the production of VAT dyes, dyeing and whitening of ice dyeing. 4. Used as an adsorbent to remove hydrogen sulfide and carbon dioxide. 5. Potassium carbonate mixed with soda ash can be used as dry powder extinguishing agent. 6. It can also be used as auxiliary raw materials for acetone and alcohol production and antioxidant in rubber production. 7. Potassium carbonate aqueous solution can be used for cooking cotton and degreasing wool. 8. It is also used in the production of printing ink, photomedicine Chemicalbook, polyester, medicine, electroplating, leather, ceramics, building materials, crystal, potash soap and medicine. 9. Heavy potassium carbonate is mainly used as the glass shell raw material of picture tube, widely used as glass and special glass raw material, and used for the decarbonization of large chemical fertilizer. 10. It can be used as leavening agent in food. 11. As alkaline agent and dough improver, and can inhibit the acid of noodles, can be used for noodle food, according to the production needs of appropriate use. 12. Used for rinsing and processing of exposed photosensitive materials. 13. Fluxes for analytical reagents, reference reagents and fused silicates and insoluble sulfates.
