Applications
1. Agricultural Industry
As a potassium fertilizer, it provides essential potassium elements for plant growth, improving nutrient absorption and environmental adaptability. Its excellent water solubility allows quick potassium release while enhancing photosynthesis through CO2 production.
2. Glass Industry
Increases glass softening temperature by decomposing at high temperatures to form stable compounds with SiO2, improving thermal resistance.
3. Glaze Industry
Lowers glaze melting point for smoother application, reduces shrinkage/cracking, and increases glaze layer strength and toughness.
4. Food Industry
Food grade K2CO3 serves as a leavening agent in puffed foods (chips, popcorn) by reacting with water to produce CO2 for expansion.
Crop-Specific Benefits
For Tomatoes
Promotes fruit growth, increases yield, and enhances disease resistance.
For Capsicum
Improves quality, color, taste, and overall yield.
