Na2CaSO42

Na2CaSO42 is an inorganic chemical compound. It is a salt formed from sodium, calcium, and sulfate ions. The chemical formula indicates two sodium atoms, one calcium atom, and two sulfate groups. This compound is sometimes referred to by its mineral name, Glauberite.

Glauberite is a mineral that crystallizes in the monoclinic system. It typically forms as tabular or prismatic crystals. The mineral is known for its relatively soft nature, with a Mohs hardness of around 2.5 to 3. It is also characterized by its moderately low density. Pure Glauberite is colorless and transparent, but impurities can lead to various colors.

This compound is found in evaporite deposits, which are formed when water evaporates from lakes or seas, leaving behind dissolved salts. Glauberite is often found in association with other sulfate minerals like thenardite (Na2SO4) and gypsum (CaSO4·2H2O). Its formation is dependent on specific salinity and temperature conditions.

Na2CaSO42 can also be synthesized in laboratory settings. Its applications are limited, but it has been studied for potential uses in areas such as cement production and as a source of sulfur. However, it is not a widely produced or utilized industrial chemical. The compound is soluble in water, with its solubility being temperature-dependent. At higher temperatures, it tends to break down into thenardite and gypsum.
