About AdolfpateraiteHide

Adolf Patera
Formula:
K(UO2)(SO4)(OH)(H2O)
Colour:
Sulphur-yellow to greenish yellow
Lustre:
Vitreous
Hardness:
2
Specific Gravity:
4.24 (Calculated)
Crystal System:
Monoclinic
Name:
In honour of Adolf Patera (11 July 1819 Vienna - 26 June 1894), Austrian chemist, working in Bohemian countries, namely in Jáchymov. Patera introduced industrial processing of U-ores for winning of U colors (first was uranium yellow - urangelb); chemist and metallurgist.
Chemically related to geschieberite and zippeite.

Crystal structure contains pentagonal bipyramids of uranyl groups. They form chains extending along [010]. The bypiramids share vertices in which OH groups are located. The sulfate groups are located in the outer side of the chains, and there are bridging bidentate connections between the uranyl polyhedra. K and H-bonds link the chains. Water is located on the edges of the chains (Plášil et al., 2012).
