Potassium Carbonate, Dry

Potassium Carbonate, a strong alkali, is a white odorless solid. Among its key chemical attributes is its high solubility in water, which allows for high strength solutions. It is available in anhydrous (APC) (99.3% by weight) dry form.  At least three grades of dry potassium carbonate are recognized: glass grade, coarse granular, and fine. Major end use markets for anhydrous potassium carbonate as a percent of the total domestic market by volume are estimated to be as follows:
