Potassium Carbonate Applications
1. Agricultural Industry
As a potassium fertilizer, potassium carbonate provides essential potassium elements crucial for nutrient absorption, biochemical metabolism, and environmental adaptability. Its excellent water solubility allows rapid potassium delivery to plants while releasing CO₂ to enhance photosynthesis.
2. Glass Industry
Potassium carbonate 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
In glazes, potassium carbonate lowers melting points, promotes smoother flow, reduces shrinkage and cracking, while increasing glaze layer strength and toughness.
4. Gas Refining
UNID Potassium carbonate effectively removes acid gases (CO₂, H₂S) from natural gas streams by forming stable salts. It's also used in carbon capture processes to reduce greenhouse gas emissions from industrial facilities.
