摘要：

ZnO, Nb2O5 and ZnO-Nb2O5 doped tin dioxide based ceramics prepared by the pressureless sintering have been investigated as function of sintering character and electrical property. The microstructure and the phase constitution was measured by scanning electrical microscope and XRD. The results indicate that ZnO can improve the volume density of the materials, but cannot decrease the electrical resistivity signally, the optimal content of ZnO was 0.5wt%-0.75wt%; Nb2O5 can signally decrease the electrical resistivity, but don't effectively improve the volumn density of the materials. The tin dioxide based ceramics doped with 0.5wt%ZnO-1.5wt%Nb2O5 and sintered at 1450°C has high performance; the volume density was 6.61 g/cm3, the electrical resistivity was 867.84 Ω&middotcm.
