Description

Sodium Carbonate is a fundamental inorganic salt and a versatile industrial alkali, also known as soda ash. It serves as a critical raw material and processing agent across numerous manufacturing sectors due to its efficacy in pH adjustment, water softening, and chemical synthesis. This compound is essential for industries including glass manufacturing, chemical production, water treatment, and detergent formulation. We supply high-purity Sodium Carbonate CAS NO 497-19-8 to meet the stringent demands of global industrial applications.

Application

• Glass Manufacturing: A primary raw material (flux) to lower the melting point of silica in the production of container, flat, and specialty glass.
• Chemical Synthesis: Used as a precursor and pH regulator in the manufacture of sodium bicarbonate, sodium silicates, chromates, and other sodium compounds.
• Water Treatment: Employed for pH correction, alkalinity adjustment, and as a precipitating agent to remove hardness ions like calcium and magnesium.
• Detergent & Soap Production: Acts as a builder to enhance cleaning efficiency, soften water, and maintain optimal pH in laundry and cleaning products.
• Pulp & Paper Industry: Utilized in pulping and bleaching processes, and for pH control in papermaking.
• Metallurgy: Functions as a flux in ore refining and metal extraction processes.
• Food Processing (FCC Grade): Approved for use as an acidity regulator, raising agent, and stabilizer in various food products.
• pH Buffer & Laboratory Reagent: Used in analytical chemistry and as a standard buffer component.

Quality Control

Our Sodium Carbonate is produced and tested under a rigorous quality management system. We offer various grades, including Technical, Food (FCC), and high-purity grades, with specifications tailored to meet industry-specific requirements. Each batch is accompanied by a Certificate of Analysis (COA) to ensure traceability and compliance with agreed-upon parameters. Certifications such as ISO and REACH compliance are supported upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container must be kept tightly sealed to prevent caking and moisture absorption. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from strong acids.
