Dense Soda Ash (Na₂CO₃) is widely used in glass manufacturing, pulp and paper production, dyes, textiles, water treatment, and chemical industries. In the glass industry, it acts as a primary flux to improve heat resistance and transparency. In water treatment, it helps adjust pH, soften hard water, and remove impurities. It is also a key raw material for producing sodium carbonate derivatives and other industrial chemicals.

The main difference lies in density, particle size, and Na₂CO₃ content. Dense Soda Ash has a higher sodium carbonate content (≥99%) and larger, denser particles, making it ideal for glass production and industrial chemical manufacturing. Light Soda Ash has finer, lighter particles and is commonly used in detergents, daily chemicals, and food industries. Choosing the right type can improve production efficiency and reduce raw material waste.
