Product Description
Potassium carbonate
has anhydrous or crystalline product containing 1.5 molecules. Anhydrous is white granular powder, crystalline product is white translucent small crystals or granules, odorless, with strong alkaline smell, relative density 2.428 (19ºC),melting point 891ºC, solubility in water is 114.5g/l00mL (25ºC) ), easy to absorb moisture and deliquescence in humid air.Dissolved in 1mL of water (25ºC) and about 0.7mL of boiling water, after the saturated aqueous solution is cooled, a glassy monoclinic crystal hydrate is precipitated, the relative density is 2.043, the crystal water is lost at 100ºC, the pH value of 10% aqueous solution is about 11.6, insoluble in ethanol and ether.

Application
1.Potassium carbonate can be used in glass, printing and dyeing, soap, enamel, preparation of potassium salt, synthetic ammonia carbonylation, color television industry, food as swelling agent; As gas adsorbent, dry powder fire extinguishing agent, rubber anti-aging agent, etc.; Used for washing and processing of exposed photosensitive materials.
2.Mainly used for analytical reagents. Such as high purity analysis, emission spectrum analysis. Can also be used for silicate and insoluble sulfate flux, organic liquid absorbent and electroplating, chemical fertilizer, photography industry.
3.It is used in the manufacture of picture tube glass shell in electronic industry, decarbonization of chemical fertilizer production, potassium salt manufacturing, used as analytical reagent, flux, and also used in the preparation of various potassium salts; Fluxes for analytical reagents, reference reagents and fused silicates and insoluble sulphates.
4.Chemical experiments do desiccant. It is moderately absorbent and can form potassium carbonate with two crystalline waters (K2CO3·2H2O), but interacts with water more slowly. Suitable for dry alcohol, ester and other neutral organic matter as well as general basic organic matter such as amines, alkaloids. However, it can not be used as a desiccant for acids, phenols or other acidic substances.
5.Alkaline agent and dough amendment, and can inhibit the sourness of noodles, can be used for pasta food, according to the production needs of appropriate use. Used in the production of optical glass, can improve glass transparency, strength and refractive coefficient.
