A stereo-atomic
crystal structure analysis of AWO4
(A = Ca, Cd, Pb, Zn) crystals was
carried out. The program package TOPOS was used for the calculation. The
migration path of the W ions in AWO4
compounds at room and higher temperatures was visualized. The conditions for
ionic conductivity in crystals with scheelite-type structure were discussed.
Probable migration pathways calculated at RT
for the W ions in PbWO4 using crystal data from the literature and
the characteristic junction of migration pathways (inset).
