Bleiphospat sowie isotype Arsenate und Vanadate zeigen jeweils eine ferroelastische Phasenumwandlung von einer monoklinen in eine rhomboedrische Paraphase.
Pb läßt sich durch Kationen ohne freies Elektronenpaar mit der Oxidationszahl + 2 substituieren.
Dies führt zu einer Renormierung der ferroelastischen Transformation.
www.ruhr-uni-bochum.deLead phosphate as well as isotpyic arsenates and vanadates show a ferroelastic phase transition from a monoclinic to a trigonal phase in each case.
Pb can be replaced by cations without lone pair and oxidation grade + 2.
This leads to normalization of the ferroelastic transformation.
