Meitnerite

This page is currently not sponsored. Click here to sponsor this page.
Photo of Lise Meitner
Formula:
(NH4)(UO2)(SO4)(OH)·2H2O
Colour:
slightly greenish yellow
Lustre:
Vitreous
Hardness:
2
Specific Gravity:
3.320 (Calculated)
Crystal System:
Triclinic
Name:
Named in honour of Lise Meitner (7 November 1878 – 27 October 1968), an Austrian-Swedish physicist who worked on radioactivity and nuclear physics. Otto Hahn and Meitner led the small group of scientists who first discovered nuclear fission of uranium. Her exclusion from the 1944 Nobel Prize in Chemistry for nuclear fission (that was awarded exclusively to her long-time collaborator Otto Hahn) is considered unfair nowadays.
Structurally related to johannite.

Contains uranyl sulfate sheets based on the phosphuranylite anion topology. The interlayer region contains an NH4+ group and two H2O groups.
