Heavy Soda Ash (CAS 497-19-8) is the dense grade of sodium carbonate, a white, odorless powder with consistent purity, whose larger particles reduce dusting and support even flow in automated dosing, serving glass production, detergents, chemical synthesis, metallurgy and water treatment. Its consistent purity makes it a preferred raw material for large-scale formulation and production operations.

Heavy Soda Ash
Applications
Used heavily in glass production; as a builder in detergent and cleaning formulations; in chemical synthesis for sodium-based compounds; in metallurgy as a flux; in water treatment for pH adjustment; and in pulp, textiles, and soap manufacturing. Favoured where controlled particle size aids automated dosing.
Safety & Risks
Irritant to eyes, skin, and respiratory system. Use dust control and PPE. Stable under normal conditions but reacts strongly with acids, releasing CO₂. Maintain dry storage to avoid caking.
Packaging
Supplied in 50 kg sacks or 1000 kg FIBCs with PE liners. Store on pallets in dry, covered areas with minimal humidity exposure.
