Abstract
The VO2.000±x nano-grain ceramics were prepared by sintering VO2.000±x nano-powders in Ar atmosphere. The influence of stoichimetric ratio of VO2.000±x (0 ≤ x < 0.050) ceramics on the phase transition heat (ΔH) and resistivity jump of VO2.000±x ceramics in the vicinity of transition temperature (Tc) was investigated. The |ΔH| and resistivity jump had similar relation with stoichimetric ratio of VO2.000±x, the |ΔH| and resistivity jump of stoichimetric VO2.000 were the highest in VO2±x nano-grain ceramics. VO2.000 nano-grain ceramics held the good electrical properties of VO2 materials, and its resistivity jump was about 700 times.
