Thenardite - Saltwiki

The only stable forms of sodium sulfate are the decahydrate and the anhydrite (thenardite). The generation of mirabilite by recrystallization of the salt from an aqueous supersaturated solution occurs at 32.4°C. In particular, the transition from thenardite to mirabilite and the incorporation of 10 water molecules in the crystal lattice causes a volume expansion of 320%. This transition

Sodium sulfate - Wikipedia

The world production of sodium sulfate, almost exclusively in the form of the decahydrate amounts to approximately 5.5 to 6 million tonnes annually (Mt/a). In 1985, production was 4.5 Mt/a, half from natural sources, and half from chemical production. After 2000, at a stable level until 2006, natural production had increased to 4 Mt/a, and chemical production decreased to 1.5 to 2 Mt/a, with a total of 5.5 to 6 Mt/a. For all applications, naturally produced and chemically pr

Sodium sulfate - Sciencemadness Wiki

24.11.2021  Sodium sulfate occurs naturally as the minerals thenardite (anhydrous Na 2 SO 4) and mirabilite (Na 2 SO 4 10H 2 O). Both forms appear depending on the weather conditions. Preparation. Sodium sulfate can be prepared by reacting a sodium salt or hydroxide with sulfuric acid or another soluble sulfate. Na 2 CO 3 + H 2 SO 4 → Na 2 SO 4 + H 2 O ...

Crystallization damage by sodium sulfate - ScienceDirect

01.04.2003  On the other hand, sodium sulfate can develop particularly large crystallization pressures. The first convincing argument for this idea was presented by Chatterji and Jensen . They noted that the solubility of thenardite becomes increasingly larger than that of mirabilite below 32 °C. Therefore, any porous material containing thenardite that ...
