Large volume collapse observed in the phase transition in cubic PbCrO 3 perovskite

When cubic PbCrO 3 perovskite (Phase I) is squeezed up to ∼1.6 GPa at room temperature, a previously undetected phase (Phase II) has been observed with a 9.8% volume collapse. Because the structure of Phase II can also be indexed into a cubic perovskite as Phase I, the transition between Phases I an...
