摘要VO2(B) was synthesized via a facile hydrothermal process using V2O5 and oxalic acid. The crystal structure and the phase transition of VO2(B) during elevated temperatures in N-2 were investigated by in situ X-ray diffraction (XRD). Meanwhile, the morphologies and the crystal structures of the samples obtained by annealing at different temperatures were characterized by Field emission scanning electron microscopy (FE-SEM), XRD and Raman spectroscopy, respectively. The results show that the as-synthesized nano platelet-like monoclinic VO2(B) irreversibly transforms into submicron and micron subsphaeroidal tetragonal VO2(R) between 430 and 700 degrees C. The as-obtained VO2(R) starts to decompose and form Magneli phases VnO2n-1 (3 <= n <= 9) series compounds at similar to 1000 degrees C, and totally transfers into a corundum V2O3 sintered block at ca. 1200 degrees C.
