Bismuth-lead oxide, a new highly conductive oxygen materials

The transport properties of an oxygen-deficient solid solution containing lead and bismuth oxides have been investigated. The conductivity is larger than 1 (ω× cm)−1 at 600 °C. Thermogalvanic measurements confirm that no significant electronic contribution occurs in the range 1–10−3atm p O2. The heat of transport of O2− ions is calculated and is in agreement with the activation energy of conduction
