Potassium carbonate (potash) K2CO3 is potassium and carbonic acid neutral salt. Potassium carbonate is a white crystalline substance, very soluble in water. Former name of the salt is potash, from here comes English name. Potash is one of the most ancient salts known to people.


Prior to XX century, in Europe potash (potassium carbonate) was one of the most critical industrial chemical reagents. It was produced by aqueous extraction from vegetable ash followed by purification to the level required. The production of potassium carbonate was focused in the places rich in forest, somewhere in Europe, but primarily in Russia and North America. In industry, potassium carbonate (potash) is primarily produced from potassium salts or as a by-product of nepheline processing to alum earth.


Potassium carbonate (potash) is used as follows:

  • in construction (as an antifreezing agent),
  • in glass industry,
  • in electrovacuum industry,
  • in chemical and other industries,
  • was used for production of woolen cloth, soap, glass appreciable varieties, paints, in currying, etc.
