Thenardite Saltwiki

Both thenardite and mirabilite occur as natural minerals. In nature sodium sulfate occurs in mineral waters in the form of double salts, as deposits of former salt lakes. The hydrated sodium sulfate was first described by Glauber in 1658 where he called it "sal mirabilis". Mirabilite is also known as "Glauber's salt" in honor of its discoverer.

THENARDITE (Sodium Sulfate) Galleries

Thenardite is one of several non-marine evaporite Sulfate Class minerals. It is easily dissolvable in water and specimens should be stored with desiccant. Sulfates in general tend to be more soluble than most of the other mineral classes and simple sodium salts, such as thernardite, are always soluble.

Thenardite mineral Britannica

Thenardite, any of a type of sodium sulfate mineral (Na 2 SO 4) that has been deposited as an evaporation product near salt lakes and playas, as in the arid regions of northern Africa, Siberia, Canada, and the western United States. It is widespread as an efflorescence on arid soil and as a crust in volcanic fumarole deposits.

Sodium sulfate anhydrous, also known as thenardite, has a formula of Na2SO4. It has an appearance of white crystalline solid and is chemically very stable. It is unreactive toward most oxidizing or reducing agents at normal temperatures. In addition to that, it can be converted to sodium sulfide at high temperature by carbo-thermal reduction.

Mirabilite 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
