A method is described whereby thermal conductivity and diffusivity can be determined continuously from measurements of the temperature difference between the top and base surfaces of a cylindrical specimen at quasi-steady state performed during heating at constant rate. The technique developed, named the "scanning temperature method", is applicable to small samples of millimeter size. The thermal conductivity and diffusivity of single- and poly-crystal alumina were measured by this method over temperatures ranging from 423 to 873K, with precisions of ±5 and ±10%, respectively. The results agreed fairly well with previously reported values. Errors due to thermal contact resistance, heat leakage and transient effect are discussed.
