Potassium Carbonate Powder, Granule K2CO3, CAS NO. 584-08-7
Potassium carbonate is an inorganic compound with chemical formula K2CO3 and molecular weight of 138.206. It appears as a white crystalline powder or granular with a density of 2.428g/cm³ and melting point of 891℃. Highly soluble in water (forming alkaline solution) and insoluble in ethanol, acetone, and ether. Potassium carbonate has strong hygroscopic properties and reacts with atmospheric carbon dioxide and moisture to form potassium bicarbonate. Proper sealing is required for storage.

Industrial Applications
1. Agricultural Industry
As a potassium fertilizer, provides essential potassium elements crucial for nutrient absorption, biochemical metabolism, and environmental adaptability. Its excellent water solubility allows rapid potassium release while enhancing photosynthesis through CO₂ emission.
2. Glass Industry
Increases glass softening temperature by decomposing at high temperatures to form stable compounds with SiO₂ and other oxides, improving thermal resistance and melting point.
3. Glaze Industry
Lowers glaze melting point, promotes smoother flow, reduces shrinkage/cracking, and enhances glaze layer strength and toughness.
4. Petrochemical Industry
Removes acid gases (CO₂, H₂S) from natural gas streams by forming stable salts. Used in carbon capture processes to reduce greenhouse gas emissions from industrial facilities.
Packing and Shipping
Storage Guidelines
- Store in dry, ventilated areas away from moisture
- Avoid outdoor storage or air exposure
- Protect from rain during loading/unloading
- Maintain dry packaging free from contaminants
- Separate from acid substances during transport
- Use water as fire extinguishing agent
