About PertlikiteHide

Formula:
K2(Fe2+,Mg)2Mg4Fe3+2Al(SO4)12 · 18H2O
Crystal System:
Tetragonal
Member of:
Name:
In honour of Franz Pertlik (b. 1943), Professor of Mineralogy and Crystallography, University of Vienna, Austria, in recognition of his extensive work on the crystal chemistry of minerals.
Voltaite Group. Chemically related to magnesiovoltaite. One of a few ferrous-ferric sulfate minerals, by bílinite, copiapite, römerite (purely Fe minerals), metavoltine, and voltaite.

Tetragonal-pseudocubic due to ordering of Fe and Mg.

An apparently cubic (a = 27.220 Å) pertlikite-related mineral with the formula [K0.73(NH4)0.27]2(Mg,Al,Fe)62+(Fe0.93Al0.07)23+Al(SO4)12·18H2O and unknown Fe(II):Fe(III) ratio was described by Witzke et al. (2015).
