Soda Ash Light is a fundamental inorganic chemical essential to numerous industrial value chains. Its production process and quality specifications—particularly purity and consistent physicochemical properties—are key determinants of performance in downstream manufacturing processes, making it a critical baseline material in global chemical supply networks.

SODA ASH LIGHT

Also known as light sodium carbonate (Na₂CO₃), is a fine white powder characterized by its low bulk density (0.5–0.6 g/cm³), high alkalinity, and rapid exothermic dissolution in water. This product offers consistent purity, reliable reactivity, and favorable handling properties due to its uniform particle size and excellent solubility profile.

Application Area
Chemical Property

Glass Industry:

As an important raw material for glass melting, it can lower the melting point of glass and improve its transparency, and is used in the production of flat glass and glass bottles and jars

Detergents and Daily Chemical Products:

In the formula for synthetic detergents, it is used as an alkaline additive to enhance stain removal ability; it is also used in soap manufacturing to neutralize fatty acids

Food Processing:

As a food additive, it is used for fermenting pasta, tenderizing meat products, and adjusting the pH value of food (in accordance with food grade standards).

Chemical and Pharmaceutical:

Used for the production of chemical products such as caustic soda, baking soda, borax, etc.; used as buffering and neutralizing agents in the pharmaceutical industry

Metallurgy and Textile:

Used for ore flotation in metallurgy; used as a softener in the textile industry to improve dyeing and finishing effects

Various reactions

Reacting with acid

Reacting with strong acids (such as hydrochloric acid) or weak acids (such as acetic acid) to produce CO ₂ and sodium salts, for example:

Na₂CO₃ + 2HCl → 2NaCl + CO₂↑ + H₂O

Application: Laboratory production of CO ₂, neutralization of acidic wastewater, food leavening (gas production causes dough to expand).

The aqueous solution is alkaline

Due to the strong alkalinity (pH ≈ 11-12) of the hydrolysis reaction (CO₃² ⁻+H ₂ O ⇌ HCO₃⁻+OH ⁻), it can be used for:

Removing oil from detergent (alkaline conditions promote saponification reaction)

Adjusting the pH value of dyeing baths in the textile industry.

Double decomposition reaction with salt

Reacting with salt solutions such as CaCl ₂ and MgSO ₄ to form insoluble carbonate precipitates, such as:

Na₂CO₃ + CaCl₂ → CaCO₃↓ + 2NaCl

Application: Removing calcium and magnesium ions in water treatment (softening water quality).

Thermal Stability

At high temperatures (>850 ℃), it slightly decomposes into Na ₂ O and CO ₂, with much higher stability than baking soda (NaHCO3), making it suitable for high-temperature scenarios such as glass melting (kiln temperature above 1500 ℃).

Reacting with organic compounds

Under alkaline conditions, oil can be saponified (producing soap components) and cellulose can be expanded, which is applied in soap making and textile dyeing pretreatment.

FAQ

How to store light soda ash?

It should be stored in a dry and ventilated warehouse, away from acidic and humid environments, and sealed in packaging to prevent moisture absorption and clumping.

Is there a difference between light soda ash and edible soda ash?

Edible soda ash belongs to food grade light soda ash and must comply with the GB 1886.1-2015 standard, with lower impurities (such as heavy metals) content. Industrial grade light soda ash cannot be used for food processing.

What is the chemical composition and specification of your Soda Ash Light?

Our Soda Ash Light is a high-purity product, typically containing ≥ 99.2% Na₂CO₃. Key specifications include:
Na₂CO₃ (Sodium Carbonate): ≥ 99.2%
NaCl (Sodium Chloride): ≤ 0.5%
Iron (Fe): ≤ 0.0035%
Water Insolubles: ≤ 0.03%
Bulk Density: 0.5 – 0.6 g/cm³
Mesh Size: Primarily passes through 100 mesh

How do you ensure consistent quality and purity in your production process?

We employ a rigorous quality control system from raw material sourcing to final packaging. Our production process is monitored with advanced analytical technology, and every batch is tested in our in-house laboratory to ensure it meets strict international standards (like ISO) and our own high specifications.

Is your Soda Ash Light compliant with food-grade or pharmaceutical-grade standards?

We produce standard industrial-grade Soda Ash Light. For applications requiring food-grade (e.g., FCC Grade) or pharmaceutical-grade (e.g., USP Grade) sodium carbonate, please contact our sales team. We can discuss your needs and provide the appropriate certified product.

What is the current state of the soda ash market? What factors will drive its future price?

The market’s core driver is shifting from demand to cost, with the price floor increasingly set by the cash costs of high-cost producers, particularly those using the ammonia-soda and dual salt processes.
