Potassium Carbonate


Potassium Carbonate may be monoclinic crystal, white powder, granular crystal or prill. The relative density is 2.428 and the melting point is at 891 degree C .It is easily soluble in water forming a slightly alkaline solution. It is insoluble in alcohol and ether. It has strong hygroscopicity. It easily cakes and turns into Potassium Bicarbonate through absorbing carbon dioxide when exposed to the air for a long time.

It can also be used as the auxiliary material of acetone, and alcohol production and the antioxidant in the production of rubber. Its aqueous solution can be used for the scouring of cotton and the degreasing of wool. In addition, it can also be applied to the production of inks, pharmaceutical for photography, polyester, electroplating, leather, ceramic, building materials, crystal, potassium soap and medicine. Heavy potassium carbonate is mainly used as the raw material of production of kinescope glass shell and is widely used as the raw material of glass and special glass materials as well as being used for the decarbonization of chemical fertilizer.
