Properties:

Industrial-grade potassium carbonate (K₂CO₃) is a white, granular or powdered solid that is highly soluble in water, forming a strongly alkaline solution (pH ~11.6). It has a melting point of 891°C and exhibits hygroscopic properties, readily absorbing moisture and carbon dioxide from the air. The compound is stable under normal conditions but requires sealed storage to prevent clumping and degradation.

Primary Industrial Uses:

Glass Manufacturing - Essential fluxing agent in production of specialty glass (optical, TV/float glass), lowering melting temperatures and enhancing clarity.

Chemical Industry - Used as a key raw material for producing other potassium compounds, dyes, pigments, and photographic chemicals.

Fertilizer Production - Source of potassium in compound fertilizers for agricultural applications.

Detergents & Soaps - Functions as a builder/alkalinity agent in industrial cleaning formulations.

Textile & Dyeing -Fixing agent and pH buffer in textile processing.

Other Applications - Electroplating, tanning, ceramics, and as a CO₂ absorbent in gas purification systems.
