Sourcing Potassium Carbonate? ChemicalDekho connects you with primary manufacturers like GACL and major importers. Secure high-purity crystals for glass, food, and agricultural formulations.
Potassium Carbonate (CAS 584-08-7) is indispensable for manufacturing television screens and laboratory glassware (borosilicate) to provide clarity and heat resistance. In agriculture, it is a high-solubility source of potassium for liquid fertilizers. In the food industry (E501i), it is used for alkalizing cocoa powder and as a leavening agent.
Verified listings ensure low levels of iron and chlorides, critical for optical glass and electronic applications.

Causes skin and eye irritation. Harmful if swallowed. Highly alkaline (pH ~11.5). Deliquescent (absorbs water until it dissolves).
Soda Ash is Sodium Carbonate. Potassium Carbonate is its potassium equivalent. K2CO3 is much more soluble in water and provides potassium ions which are better for plant health and specialty glass clarity.
It is cocoa powder treated with Potassium Carbonate to neutralize its natural acidity, giving it a darker color and milder flavor.
It is a mild desiccant that is compatible with many organic molecules where stronger agents like Calcium Chloride might react with the solute.
Technically 'Potash' refers to various potassium salts, but Potassium Carbonate was the original 'Pot-Ash' (made from wood ashes in a pot).
