Learn About Sodium Sulfate-Functions and Uses of Magnesium Sulfate
Physical and Chemical Properties of Sodium Sulfate
Sodium sulfate (Na₂SO₄) is primarily used in the pharmaceutical, industrial, light industrial, textile, and glass sectors.
Basic Appearance: Industrial sodium sulfate, also known as thenardite or anhydrous salt cake, appears as colorless transparent orthorhombic crystals or uniform white crystalline powder. Decahydrate sodium sulfate presents granular crystal form at room temperature. After our refined crystallization treatment, the product features clean surface, uniform granularity and no impurity spots, meeting international commercial grade standards.
Solubility Traits: Sodium sulfate exhibits unique temperature-dependent solubility, with rapid solubility rise within low-temperature range and gradual saturation in high-temperature environments. It is soluble in water and glycerol, and completely insoluble in ethanol and organic solvents, forming the core physical basis for our low-energy evaporation and selective crystallization technology.
Stability & Hygroscopicity: The product features excellent chemical inertness and room-temperature stability, with no oxidation or decomposition reaction under conventional storage conditions. Anhydrous sodium sulfate has extremely low hygroscopicity, while decahydrate products easily weather and lose crystal water in dry air, enabling flexible grading and customized production for diverse scenarios.
Thermal Characteristics: Sodium sulfate has a melting point of 884℃ and maintains stable chemical structure under conventional industrial heating temperatures. It features gentle dehydration transition and no harmful gas decomposition during processing, with safe and controllable industrial production conditions.
Product Grading Features: Our customized sodium sulfate products achieve stable purity grading, low water-insoluble content and controllable bulk density. We can adjust powder and particle proportion to adapt to detergent, papermaking, chemical synthesis and pharmaceutical auxiliary industrial standards.
