Product Name:Sodium metasilicate pentahydrate
English Name:Sodium metasilicate pentahydrate
CAS No.:10213-79-3
Aliases:Pentahydrate sodium metasilicate, Sodium silicate pentahydrate
Molecular Formula:Na2SiO3·5H2O
Physical Properties:White granular crystals with buffered alkalinity and capability of binding calcium and magnesium ions, especially with a magnesium ion binding capacity greater than 260 mg MgCO2/g (35°C, 20 min). Solubility in water at 20°C is 50 g/100 g water; melting point 72°C; soluble in water, insoluble in ethanol. It exhibits strong detergency, neutralizes acidic soils, emulsifies fats and oils, has deflocculating effect on inorganic substances, and provides corrosion protection for light metals.
Uses:Widely used in household laundry powders, laundry pastes, industrial detergents, food cleaning agents, metal cleaners, textile processing and paper de-inking. It is an important builder for concentrated detergents and phosphate-free or low-phosphate detergents. Also applied in the ceramic and petroleum industries.
Technical Specifications:
Purity: 99%
Appearance: granular
Melting point: 72°C
Solubility at 20°C: 50 g/100 g water
Magnesium ion binding capacity: >260 mg MgCO2/g (35°C, 20 min)
