Abstract
The formation mechanism of zinc-antimony spinel for V2O 5/Sb2O3 precursor, SbVO4 or Sb 2O3 doped ZnVSb based varistor ceramics were studied by means of DSC-TGA and XRD techniques. The results show that the forming temperature of ZnSb2O6, the intermedium product of the zinc-antimony spinel formation reactions, was decreased by Sb doping mode changes and the spinel formation within the as studied ZnVSb based ceramics was promoted.
