Product Description
Soda Ash Dense is a non-corrosive, odorless, alkaline powder with a bulk density of 950–1,100 kg/m³. It appears as a white granular solid with high solubility in water (33.2 g/100 mL at 35.4°C), forming a strongly alkaline solution (pH ~11.5 for 1% solution). The material is hygroscopic, absorbing moisture and carbon dioxide from air, and reacts exothermically with acids.

Application Sectors and Industries of Soda Ash Dense
Glass Manufacturing
Soda Ash Dense reduces silica’s melting point from 2,300°C to 1,500°C, enabling energy-efficient production of flat glass (windows, automotive), container glass (bottles), and fiberglass. It enhances clarity and thermal stability in final products.
Detergent & Soap Production
Acts as a water softener by sequestering calcium/magnesium ions in hard water, improving surfactant efficiency in powdered detergents. Neutralizes acidic soils and maintains alkaline conditions for optimal cleaning.
Water Treatment
Adjusts pH in municipal and industrial wastewater systems, neutralizes acidic effluents, and precipitates heavy metals. Prevents pipe corrosion in drinking water infrastructure.
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 cotton mercerization, enhancing dye affinity and fabric strength. Removes impurities in synthetic fiber production and stabilizes dye baths.
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 stages.
Food Processing
Food-grade Soda Ash Dense (E500) is used in cocoa alkalization, noodle texture improvement, and pH adjustment in bottling. Complies with FCC standards.
Mining
Processes uranium ores, recovers lithium from brines, and stabilizes tailings ponds through pH control. Essential in beneficiation of cobalt and zinc ores.
Flue Gas Desulfurization
Neutralizes sulfur dioxide (SO₂) emissions from coal-fired power plants, converting them into sodium sulfite/sulfate for safe disposal.
