摘要

采用共沉淀法成功合成了铈基陶瓷材料（M0.01Ce0.99O2），并在1000℃空气中烧结4h。在500-750℃的空气中，用交流阻抗谱法测量了这些体系的电导率；经证实，少量引入铜、铋、钐、钕等掺杂剂可使该参数提高4-5倍。然而，铋或钕是最佳的掺杂剂，因为它们具有更高的电导率和氧化物离子转移数。

Electrical conductivity of low-doped ceria-based ceramics

Ceria-based ceramic materials (M0.01Ce0.99O2) were successfully synthesized by the co-precipitation method and sintered at 1000 °C for 4 h in air. The electrical conductivity of these systems was measured by AC impedance spectroscopy at 500-750 °C in air; it has been established that the small introduction of dopants such as copper, bismuth, samarium, and neodymium increased this parameter by 4-5 times. However, the optimal dopants are Bi or Nd due to their higher conductivity and oxide ion transference number.
