Sodium sulfate decahydrate (Glauber′s salt, mirabilite, Na2SO4·10H2O) is the decahydrate salt of sodium sulfate. Its crystal structure has been investigated by single-crystal neutron diffraction studies. Its crystallization enthalpy has been evaluated. It can be synthesized by reacting MnSO4, thiophene-2,5-dicarboxylic acid and sodium glutamate.

1. Water treatment:
Sodium sulfate decahydrate can be used in water treatment processes, especially in removing metal ions and other impurities from water. It can effectively react with metal ions to form insoluble precipitates.
2. Detergents and washing powders:
In detergents and washing powders, sodium sulfate decahydrate is used as an auxiliary agent to help improve the cleaning effect. It can be used as a water hardness regulator in detergents to prevent minerals in water from adversely affecting the washing effect.
3. Papermaking industry:
In the papermaking process, it can be used as a neutralizer or additive to adjust the pH of pulp and improve the quality of paper.
4. Glassmaking: In the glass production process, sodium sulfate decahydrate can be used as a flux to help lower the melting point and improve the melting efficiency.
5. Desiccant: In some cases, sodium sulfate decahydrate can also be used as a desiccant with strong hygroscopicity and is used for drying in laboratories or industries.
