Nm. Olekhnovich et al., STRUCTURAL AND DIELECTRIC-PROPERTIES OF PBGEO3-PBZRO3 METASTABLE SOLID-SOLUTIONS WITH PEROVSKITE STRUCTURE, Inorganic materials, 32(3), 1996, pp. 331-335
PbGeO3 was found to undergo a sequence of structural phase transitions
at high pressures and temperatures. In the PbGeO3-PbZrO3 system, we o
btained a continuous series of metastable solid solutions with a perov
skite structure persisting up to 700-800 K at ambient pressure. PbZrxG
e1-xO3 metastable perovskites are ferroelectrics exhibiting similar co
mposition dependences of Curie temperature and lattice parameters.
