About Thénardite
Louis Jacques Thénard
Formula:
Na2SO4
Colour:
Colourless, very light grey, light brown; colourless in transmitted light
Lustre:
Vitreous, Resinous
Hardness:
2½ - 3
Specific Gravity:
2.664
Crystal System:
Orthorhombic
Name:
Thenardite was named by J.L. Casaseca in 1826 and published both in French and English. In both articles, the mineral name was without the accent mark, even though the family name Thénard is spelled with an accent. Casaseca was a professor of chemistry at the university of Madrid (Spain), and he named the mineral after his teacher and mentor Louis Jacques Thénard (1777-1857), Professor of Chemistry, University of Paris (France). Both spellings, thenardite and thénardite, were used in literature until 2014, when IMA proposal 14-A was accepted and the mineral name "thenardite" became thénardite, in agreement with the original spelling of the family name.
Dimorph of:
Five polymorphs known (compare metathénardite).
May occur as a dehydration product of mirabilite. See also 'UM1962-08-SO:HNa'.
As shown by experiments of Africano et al. (2002), it may deposit from volcanic gas in high fO2 conditions during cooling from ca. 800 down to 400°C, together with aphthitalite.
