Measurements of porous aluminum oxide thermal properties

Abstract

Abstract A method of measurement of the thermal performances of composite materials on the base of the porous aluminium oxide is described. The method takes into account the heat inhomogeneity, the material inhomogeneity and anisotropy as well as specimen’s surface radiation. Investigations of the thermophysics properties of the porous substrate fabricated with using of the electrochemical aluminium oxide technology vs. temperature and long staying in a climate chamber were fulfilled. The tests demonstrated that the climatic impact does not influence on the high thermophysics properties of the aluminium oxide material that have extremely high thermal conductivity ≤ 120 W/(m·K).
