Products Description of Potassium carbonate CAS#584-08-7

Potassium carbonate (molecular formula: K2CO3), additionally regarded as potash or pearl ash, seems as a white powder or as colorless strong crystal with salty style and deliquescence. It can be dissolved in water to structure a strongly alkaline solution. However, it is insoluble in natural solvents such as ethanol.

Product Application of Potassium carbonate CAS#584-08-7

Potassium carbonate can be used in the production of optical glass because it can enhance the transparency, strength and refractive index of the material. It can also be used as a welding rod to prevent arc breakage during welding. Further applications of potassium carbonate include its use as a VAT dye and as a de-whitening agent for ice dyeing. It can be used as an absorbent for removing carbon dioxide and hydrogen sulfide, and it can be mixed with soda ash to produce dry powder fire extinguishing agent.
