The thermoelectric coefficient of cobaltous oxide was measured as a function of temperature and oxygen activity between 1000° and 1400°C. Results conform to ideal point defect theory at high temperature and high oxygen activity. Minority electrons are detected near the low‐oxygen activity phase boundary. At low temperature and high oxygen activity, deviations from ideality are detected in that oxygen exponents of the hole concentration exceed that predicted by Ideal point defect theory.
