Abstract Ferroelastic/ferroelec. phase transitions in Cd2Nb2O7 crystals have been analyzed by means of polarized light microscopy assocd. with elec. characterization. The symmetry of the ferroelec. phase below T2 = 194 K is orthorhombic mm2(pp) with the spontaneous polarization PS parallel to [001]cub. By application of an elec. field the mm2(pp) phase remains stable in the whole temp. range of the ferroic phases below T1 = 204 K, whereas a field can induce a mm2(ss) phase below T1.
