BiFeO3 (BFO) and Bi0.8La0.1Ho0.1FeO3 (BLHFO) materials were prepared by a solid-state reaction method. The dynamic process of melting and solidification of the samples was observed in real time by high temperature polarizing microscopy. The phase composition, microstructure and element distribution of the solidified samples were analyzed by X-ray diffraction, scanning electron microscopy and energy dispersive spectrometry. It is indicated that BFO and BLHFO samples both have polyhedral Fe2O3 grains precipitated along with the melting and further grow in the cooling process. Based on the results by SEM, a continuous Bi2O3 phase is mixed with a small amount of micron-sized Fe2O3 grains and a large amount of micron-sized BiFeO3 grains. BiFeO3 grains in the undoped samples are irregular, while La-Ho doped samples form regular cubic BiFeO3 crystals. In addition, Fe2O3 grains in the co-doped sample only contain La element. La and Ho can be co-doped into BiFeO3 polyhedral grains.
