A method of synthesizing VO2 nano-powder by decomposing VOC2O4·H2O（which was made from commercial V2O5 powder deoxidized by oxalic acid） in vacuum oven pipe at 350 ℃ was developed.The powder was characterized by means of thermal analysis（TG-DSC）,X-ray diffraction spectroscopy（XRD）,transmission electron microscope（TEM） and resistance-thermometer.The results show that the powder is crystallized,the component is only VO2,the average particle size is 80～120 nm,its phase transition temperature is 68.5 ℃,and its resistance abrupt change reaches three magnitudes.
