| 摘 要： | ZnO压敏电阻陶瓷是一种典型的“晶界特性”功能陶瓷材料，材料的宏观电学特性与陶瓷的显微组织结构有密切联系。由于ZnSb尖晶石相在使ZnO基压敏电阻陶瓷显微形貌细化和均匀化方面有明显促进作用，自ZnO基压敏电阻发明以来．ZnSb尖晶石在其中的形成机理就成为该陶瓷研究领域的热点。

| Abstract: | The formation mechanism of zinc-antimony spinel for V2O5 / Sb2O3 precursor, SbVO4 or Sb2O3 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. |
