在20 ~ 1000℃范围内，对puo1.70 ~ puo2.00组成范围内的氧化钚的电阻率和热电功率进行了初步的测量。在室温下，真空烧结得到的正常的puo2 - x2o组成具有p型导电性。这一变化发生在加热到n型时，这是缺氧puo2−tx的特征。室温电阻率和低温活化能随氧含量直接变化。在较宽的氧含量范围内，puo2−x2的电子传导活化能为0.52 eV，而puo2−x2的本禀活化能为1.8 eV。
Preliminary measurements have been made on the electrical resistivity and thermoelectric power of plutonium oxide in the composition range of PuO1.70to PuO2.00from 20 to 1000° C. The normalPuO2−xcomposition which results from the vacuum sintering of PuO2has been shown to exhibit p-type conductivity at room temperature. This changes on heating to n-type which is characteristic of oxygen deficientPuO2−tx. Room temperature resistivity and low temperature activation energy varies directly with oxygen content. The activation energy for electronic conduction forPuO2−xis 0.52 eV over a wide range of oxygen content, while the intrinsic activation energy for PuO2is 1.8 eV.
