About Heinrichite
Eberhardt W. Heinrich
Formula:
Ba(UO2)2(AsO4)2 · 10H2O
Hardness:
2½
Crystal System:
Monoclinic
Member of:
Name:
Named in honor Eberhardt "Abe" William Heinrich (10 February 1918, Braunschweig, Germany - 8 July 1991, Ann Arbor, Michigan, USA), mineralogist at the University of Michigan, USA.
Autunite Group.
Unstable at room temperature and dehydrates fairly rapidly to metaheinrichite (Walenta, 1965) which may be fully transparent. Most of the specimens shown on the photos here are probably metaheinrichite.
