Sodium Carbonate At A Glance
Sodium Carbonate, commonly known as Soda Ash, is an inorganic compound manufactured through the ammonia-alkali process or derived from natural trona ore. It serves as a vital fluxing agent, lowering the melting point of silica in glass production, and acts as a key alkaline builder in industrial detergent formulations.

Sodium Carbonate Product Range
We produce two distinct physical forms of Sodium Carbonate to meet specific industrial requirements regarding bulk density, dissolution rate, and dust control.
Dense Soda Ash
Engineered for continuous glass furnace operations. The granular structure provides a higher bulk density (0.9-1.1 g/cm³), which significantly minimizes dust generation during batching and prevents segregation of raw materials before melting.
Light Soda Ash
Characterized by a fine particle size and lower bulk density (0.45-0.6 g/cm³). This structure provides a larger surface area, ensuring rapid and complete dissolution required for liquid chemical reactions and detergent powder compounding.

Our production process utilizes rigorous batch titration and spectrophotometry to ensure trace impurities remain well below industry standards. The following parameters represent our standard specification limits.
| Parameter / Item | Dense Grade | Light Grade |
|---|---|---|
| Total Alkalinity (as Na₂CO₃) | ≥ 99.2% | ≥ 99.2% |
| Chloride (as NaCl) | ≤ 0.7% | ≤ 0.7% |
| Sulphate (as Na₂SO₄) | ≤ 0.03% | ≤ 0.03% |
| Iron (Fe) Content | ≤ 0.0035% | ≤ 0.0035% |
| Bulk Density | 0.9 - 1.1 g/cm³ | 0.45 - 0.6 g/cm³ |
| Moisture Content | ≤ 0.5% | ≤ 0.5% |
| Water Insolubles | ≤ 0.03% | ≤ 0.03% |
Pre-shipment Inspection
We accommodate third-party testing (SGS, BV, Intertek) upon request to verify mass production stability before container loading.
Request Sample ApprovalCommon Challenges When Buying Soda Ash
Procurement managers frequently face supply chain and quality inconsistencies. Here is how our production and logistics framework mitigates these risks.
High Trace Iron Content
For solar glass manufacturers, iron impurities (>0.004%) cause unwanted green tints and lower light transmittance.
Solution: Our purification process guarantees Fe ≤0.0035%, ensuring high clarity for optical and solar glass.
Moisture Caking in Transit
Long ocean freights often lead to moisture absorption, causing the powder to harden and block feeding hoppers.
Solution: We use double-layered PP/PE packaging with inner liners, maintaining ≤0.5% moisture upon arrival.
Unpredictable Lead Times
Factory shutdowns due to delayed raw material delivery can cost thousands of dollars daily in lost production.
Solution: 300,000 MT capacity and strategic port warehousing allow us to guarantee 14-21 day vessel loading.

Sodium Carbonate Applications
Our product is formulated to meet the exact tolerances required by diverse industrial sectors, ensuring seamless integration into your existing production lines.
Glass Manufacturing
Dense Soda Ash is a crucial flux. It lowers the melting temperature of silica sand from 1700°C to around 1500°C, significantly reducing energy consumption in furnace operations.
Primary Use: 50% of Global DemandDetergent Industry
Light Soda Ash acts as an alkalinity builder and water softener. It provides the necessary pH environment for surfactants to effectively remove dirt and grease from fabrics.
Key Benefit: Rapid DissolutionWater Treatment
Used to adjust pH levels and soften water by precipitating calcium and magnesium ions. Essential for municipal water treatment and industrial boiler feed water preparation.
Function: pH RegulationChemical Manufacturing
A foundational raw material for synthesizing other sodium compounds, including sodium silicate, sodium bicarbonate, and sodium chromate.
Metallurgy
Utilized in the de-sulfurization and de-phosphorization of cast iron and steel. Also used in the processing of aluminum, zinc, and lead ores.
Pulp & Paper
Employed in the neutral sulfite semi-chemical (NSSC) pulping process and for adjusting the pH during the bleaching of wood pulp.
Packaging & Shipping Options
To accommodate different unloading infrastructures and MOQ requirements, we offer flexible packaging solutions. All bags feature inner PE liners to prevent moisture ingress during maritime transit.
