Sodium Sulfate

Sodium Sulfate (Na₂SO₄) is a white crystalline powder (anhydrous) or colorless transparent crystal (decahydrate). It is highly soluble in water, chemically stable, and absorbs moisture from air to form decahydrate (mirabilite).

Formula:: Na₂SO₄
CAS:: 7757-82-6 (anhydrous), 10101-63-2 (decahydrate)
Min. Order:: 25KG
Molecular Wt:: 142.04
Appearance:: Anhydrous: white crystalline powder; Decahydrate: colorless transparent crystals
Application:: Chemical Industry:
Drying agent in lab and industrial processes.
Chemical reagent in displacement reactions.
Raw material for sodium sulfide, potassium sulfate, etc.

Paper Industry:
Raw material in sulfate pulping to decompose lignin and improve pulp quality.

Textile Industry:
Dyeing aid for even dye distribution.

Detergent Industry:
Filler in laundry powders to enhance flow and stability.

Glass Manufacturing:
Clarifying agent to remove bubbles from molten glass.

Pharmaceutical Field:
Laxative for constipation relief.
Antidote for barium poisoning.
Excipient for intestinal cleansing before procedures.

Other Applications:
Water softening to remove Ca²⁺/Mg²⁺.
Analytical reagent in labs.
Packaging:: Solid: 25 kg bags (inner polyethylene lining, outer woven/laminated paper). Liquid: 200 kg drums (plastic or glass).
Storage:: Store in a dry, well‑ventilated warehouse at 15‑25°C, RH < 50%. Keep away from acids and oxidizers. Seal containers to prevent moisture uptake. Inspect packaging regularly.
Transportation:: Inspect packaging before shipment; replace any damaged. Transport in dedicated, moisture‑proof vehicles. Avoid mixing with other goods. Ensure smooth handling to prevent shocks. Personnel should wear masks, goggles, protective clothing, and gloves.
Summary:: Sodium Sulfate is a versatile inorganic salt used as a drying agent, reagent, pulping raw material, dyeing aid, detergent filler, glass clarifier, and pharmaceutical agent. Its high stability and solubility make it suitable for diverse applications, but moisture‑proof packaging and controlled storage conditions are essential to maintain quality.
