Sodium Carbonate (Soda Ash Light / Dense) CAS 497-19-8
Sodium Carbonate (Na2CO3), universally recognized as Soda Ash, is an indispensable inorganic alkaline compound utilized as a foundational feedstock across global heavy industries. Characterized as a white, odorless crystalline powder or granular solid, our high-purity Sodium Carbonate is strictly manufactured to deliver optimized chemical stability, excellent solubility, and exceptional pH regulation performance. To perfectly align with diverse downstream processing equipment, we supply both Soda Ash Light (optimized for rapid dissolution and chemical synthesis) and Soda Ash Dense (engineered for high bulk density and low-dust glass batching), ensuring rigorous compliance with international manufacturing and compounding standards.
- Effective in pH regulation and neutralization processes: Demonstrates powerful buffering capacity and precise alkalinity delivery for waste streams and chemical synthesis.
- High Structural Stability for Industrial Processes: Manufactured under stringent calcination controls to ensure low moisture absorption and excellent thermodynamic consistency during high-temperature glass melting.
- Ensures consistent quality for industrial and chemical applications: Strict batch-to-batch monitoring guarantees minimal trace heavy metals and chloride levels, preventing equipment corrosion.
Sodium carbonate Description
NAME: Sodium carbonate (Na₂CO₃)
Synonyms: Soda ash / Disodium carbonate / Calcined soda / sodium trioxocarbonate
Molecular Formula: Na2CO3
Molecular Weight: 105.988
CAS NO.: 497- 19-8
Density: 2.53
Boiling point: 1600°C
Melting point: 851 °C(lit.)
flashing point: 169.8ºC
Appearance: White odorless powder
Solubility: Soluble in water, slightly soluble in anhydrous ethanol, insoluble in propyl alcohol, soluble in glycerol.
Properties: Pure Soda Ash presents as a highly stable white powder or fine alkaline granules. Its aqueous solution undergoes significant hydrolysis, exhibiting strong alkalinity profile. It remains stable under ambient conditions but gradually absorbs moisture and carbon dioxide in open air to form sodium bicarbonate caking.
Package: Standard 25kg/50kg PP/PE woven bags with inner liners, or 1000kg jumbo bulk bags tailored for maritime container shipping.
Storage: Must be stored in a cool, dry, and optimally ventilated chemical warehouse. Keep containers hermetically sealed to prevent atmospheric moisture pickup. Store strictly isolated from incompatible acids, ammonium salts, and high-humidity zones. Ensure careful mechanical handling to mitigate packaging degradation.
About Us: As a globally verified Sodium Carbonate and synthetic alkali manufacturer, we combine decades of chemical synthesis engineering with stringent international quality protocols. Every single commercial batch undergoes rigorous testing to deliver high-performance, compliant chemical supply chains worldwide.

Sodium carbonate Applications
Soda ash is most commonly used for:
- Advanced Glass Manufacturing: In the production of float glass, container glass, and industrial tableware, our Soda Ash acts as a critical flux. It effectively lowers the melting temperature of silica sand, significantly reducing energetic overheads and enhancing the structural machinability of the molten glass matrix.
- Detergent & Soap Synthesis: Serving as a high-efficiency builder and alkaline reserve source, it optimizes surfactant performance, neutralizes acidic soils, and provides a smoother, cleaner finish in both commercial laundry detergents and heavy-duty household cleaners.
- Comprehensive Chemical Processing: Acts as a vital sodium-sourced precursor for synthesizing downstream chemical compounds such as Sodium Silicate (Water Glass), Sodium Bicarbonate, Sodium Dichromate, and various industrial triphosphates.
- Environmental & Water Treatment: Utilized globally for industrial wastewater pH adjustment, acid effluent neutralization, and metallurgical water softening processes, ensuring full compliance with environmental discharge regulations.
Frequently Asked Questions about Sodium Carbonate
Q: What is the difference between Soda Ash Light and Dense?
A: While the chemical formula is the same, Soda Ash Dense has a higher bulk density and is preferred for glass making, while Soda Ash Light is more suitable for detergent and chemical manufacturing due to its smaller particle size.
Q: How do you ensure the quality during international shipping?
A: We use double-layered moisture-proof packaging and conduct rigorous pre-shipment inspections to prevent caking and contamination during transit.
