Lévyne-Na

This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Na2,Ca,K2)[Al2Si4O12] · 6H2O
System:
Trigonal
Lustre:
Vitreous
Hardness:
4 - 4½
Name:
Named by David Brewster in 1825 in honor of Serve-Dieu Abailard "Armand" Lévy [November 14, 1794 Paris, France - July 29, 1841 Pecq near Saint-Germain, France], French mineralogist and crystallographer, Paris University, France. Lévy used the nickname "Armand", partly as a personal preference and partly to avoid anti-antisemitism. The suffix indicates the dominant exchangeable cation.
Isostructural with:
The sodium-dominant member of the Lévyne series.

9 : SILICATES (Germanates)
G : Tektosilicates with zeolitic H2O; zeolite family
D : Chains of 6-membered rings – tabular zeolites
