VO2 powders were prepared by a new and simple method, which used VOSO4 as raw material to form VO(OH)2 sediment through hydrolysis process, then clean and dry the VO(OH)2 sediment, VO2 powders is produced by vacuum annealing process. XRD and XPS testing to the synthesized product show the VO2 content in the samples approach 100%. The electrical and optical switching properties were tested, and the results show the resistance changed near two orders of magnitude and mid-IR transmissivity changed 15% because of the phase transition.
