Product Introduction
Potassium carbonate is an inorganic compound, appearing as white crystalline powder or granular solid. It's highly hygroscopic, readily absorbing moisture from air and even deliquescing in humid conditions.
Produced via methods like the potassium chloride - carbonate process or ion - exchange, it serves as a critical basic inorganic chemical raw material. Its unique chemical properties enable wide - ranging use across multiple industries.

Product Application
Glass Industry
A key raw material, it lowers glass melting temperature and enhances transparency, strength, and chemical stability. In high - end optical glass (e.g., for electronics) and specialty glass production, it optimizes optical/physical properties, suiting precision instruments and electronic devices.
Chemical Industry
- Inorganic Synthesis: Used to make other potassium - based compounds (e.g., potassium hydroxide, potassium nitrate). For example, it reacts with calcium hydroxide to produce potassium hydroxide.
- Organic Synthesis: Acts as a base catalyst or potassium source in organic reactions. In pharmaceuticals, dyes, and synthetic resins, it drives processes like neutralization, condensation, and substitution to form target products.
Fertilizer Industry
As a potassium - rich fertilizer, it supplies vital potassium for plant growth. Potassium boosts photosynthesis, crop resistance (drought, disease), and yield/quality. Ideal for potassium - loving crops like potatoes, bananas, and cotton.
Food Industry
Used as a pH regulator, leavening agent, or stabilizer in food processing (e.g., baked goods). It reacts with acids to release carbon dioxide for expansion, adjusting taste and texture. Usage follows strict food safety standards.
Other Applications
- Textile & Dyeing: Serves as a softening and dye - fixing agent, enhancing dye brightness/fastness and fabric feel.
- Electronics: High - purity grades are used in making electronic components (e.g., lithium - ion batteries), influencing product performance and stability as electrolyte/electrode material feedstock.
