Abstract Thermal conductivity of polycrystalline La2CuO4, La2NiO4, and Nd2CuO4 was measured in the temperature range 300–1000 K. No anomaly in thermal conductivity has been observed during the semiconductor-to-metal transition of La2NiO4 or in the metallic phases of La2CuO4 and La2NiO4. A change of slope has been found, however, in the thermal conductivity of La2CuO4 at the crystallographic transition. The thermal conductivity of the oxides is mainly phononic in this temperature range.
