Description

Sodium Carbonate Decahydrate is the hydrated crystalline form of soda ash, a fundamental inorganic chemical. This compound is valued for its consistent alkalinity and solubility, making it a versatile processing agent and pH regulator across numerous industries. Key industrial users include manufacturers in the detergent, glass, chemical processing, and water treatment sectors, where it serves as a cost-effective source of carbonate ions and alkalinity.

Application

• Detergent & Soap Manufacturing: As a builder to soften water, enhance cleaning efficiency, and maintain alkalinity.
• Glass Production: A key fluxing agent to lower the melting point of silica in the manufacture of glass and fiberglass.
• Chemical Synthesis: Used as a raw material or pH adjuster in the production of sodium bicarbonate, sodium phosphates, and other sodium salts.
• Water Treatment: For pH adjustment, corrosion control, and as a precipitating agent to remove hardness ions like calcium and magnesium.
• Textile Processing: Employed in scouring and dyeing baths to neutralize acids and condition fibers.
• Pulp & Paper Industry: Used in pulping and bleaching processes as an alkaline source and for pH control.
• Food Processing (FCC Grade): As a processing aid, pH control agent, and raising agent (subject to specific grade and regulatory approval).
• Laboratory & Analytical Reagent: Used as a standard in titrations and various chemical preparations.

Quality Control

Our Sodium Carbonate Decahydrate is produced under a stringent quality management system. Product quality is verified against relevant industry specifications, which may include technical, food (FCC), or reagent (ACS) grades based on customer requirements. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metal content, and loss on drying are available for every batch upon request, ensuring full traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in original packaging or airtight containers to prevent caking and degradation due to atmospheric moisture. Keep away from strong acids.
