Thermal conductivity of polycrystalline La/sub 2/CuO/sub 4/,La/sub 2/NiO/sub 4/, and Nd/sub 2/CuO/sub 4/ was measured in the temperature range 300-1000 K. No anomaly in thermal conductivity has been observed during the semiconductor-to-metal transition of La/sub 2/NiO/sub 4/ or in the metallic phases of La/sub 2/CuO/sub 4/ and La/sub 2/NiO/sub 4/. A change of slope has been found, however, in the thermal conductivity of La/sub 2/CuO/sub 4/ at the crystallographic transition. The thermal conductivity of the oxides is mainly phononic in this temperature range.
