Industrial USES include serum protein biochemical tests, catalysts for Kjeldahl and basic materials for the production of various potassium salts such as potassium carbonate and potassium persulfate. Used as a cleaning agent in the glass industry. Used as intermediate in dye industry. Used as an additive in the perfume industry. It is also used in the pharmaceutical industry as a cathartic for the treatment of soluble barium salt poisoning.
