Ferroelec./ferroelastic dendritic single domain crystals of BiFeO3 were grown in the ferroelec. phase in a Bi2O3/B2O3/Fe2O3 flux using a platinum crucible, placed in an evacuated sealed quartz tube. Etching of the crystals shows the non-centrosym. polar character of the crystals. The single domains can be rendered ferroelastically polydomain by heating above the phase transition temp. of 1110 K and subsequent cooling or by mech. twinning using stress components along the spontaneous polarization direction, which represents the longest pseudocubic space diagonal. Mech. detwinning has also been obsd. Etching of the twinned crystals at room temp. showed no 180 Deg ferroelec. domains inside the ferroelastic domains.
