Sodium Sulfate

Sodium Sulfate Anhydrous, commonly known as Salt Cake or Thenardite, is an inorganic sulfate salt. It appears as white crystalline powder or granules, odorless and hygroscopic. Its aqueous solution is neutral to slightly alkaline with stable chemical properties, decomposable at high temperatures. It is a fundamental industrial raw material widely used in chemical, light industry, textile, and building material sectors.

1. Detergent Industry: Used as filler and builder in synthetic detergents, soaps and washing powders.
2. Glass Industry: As fluxing and clarifying agent to reduce melting temperature and remove bubbles.
3. Textile & Dyeing: As dyeing assistant and levelling agent for cotton dyeing.
4. Paper Industry: Used in pulping and cooking for kraft paper and paperboard.
5. Chemical Raw Material: For manufacturing sodium sulfide, sodium silicate, ultramarine, barium sulfate, etc.
6. Building Materials: As early-strength agent and water reducer for concrete.
7. Pharmaceutical & Food: Pharmaceutical excipient, laxative, food additive (drying agent, anticaking agent).
8. Others: Used in dyestuffs, pigments, electroplating, mineral processing, leather, analytical reagents, etc.
