Product Description
Soda Ash Light is a non-corrosive, odorless, alkaline powder with a slightly salty taste. It appears as a white crystalline solid with a bulk density of 550–720 kg/m³. Highly soluble in water (22 g/100 mL at 20°C), it forms a strongly alkaline solution (pH ~11.5 for 1% solution). While non-flammable, it reacts exothermically with acids and absorbs moisture and carbon dioxide from air.

Application Sectors and Industries of Soda Ash Light
Glass Manufacturing
Soda Ash Light reduces silica’s melting point from 2,300°C to 1,500°C, enabling energy-efficient production of container, flat, and fiberglass. It enhances clarity and thermal stability in final products.
Detergent & Soap Production
Acts as a water softener by sequestering calcium/magnesium ions, improving cleaning efficiency in powdered detergents. Neutralizes acidic soils and maintains alkaline conditions for optimal surfactant performance.
Water Treatment
Adjusts pH in municipal and industrial wastewater, neutralizes acidic effluents, and precipitates heavy metals. Prevents pipe corrosion in drinking water systems.
Chemical Synthesis
Key precursor for sodium bicarbonate, sodium silicate, and sodium percarbonate. Used in dye intermediates, battery recycling, and flue gas desulfurization.
Textile Processing
Regulates pH during mercerization of cotton, enhancing dye affinity and fabric strength. Removes impurities in synthetic fiber production.
Food Processing
Food-grade Soda Ash Light (E500) is used in cocoa alkalization, noodle texture improvement, and pH adjustment in bottling. Complies with FCC standards.
Metallurgy
Extracts metals like cobalt and vanadium from ores. Neutralizes acidic byproducts in steel production and acts as a flux in non-ferrous metal refining.
Pulp & Paper Industry
Delignifies wood pulp during kraft processing and de-inks recycled paper. Enhances brightness and reduces chemical consumption in bleaching.
Pharmaceuticals
Adjusts pH in antacid formulations and synthesizes active ingredients like sodium phenolate. Used in dialysis solutions and tablet coating.
Mining
Processes uranium ores, recovers lithium from brines, and stabilizes tailings ponds through pH control.
