The thermal properties of Sr 0,3 Ba 0,7 Ti 1-y Zr y O 3 (BST30Zr) ferroelectric ceramics with different concentrations of Zr are studied by a Photoacoustic (PA) technique and the temperature relaxation method. The results of the measurements shows that the thermal conductivity of the samples increases linearly with the content of Zr, a behavior explained using the Maxwell-model for the dependence of this magnitude from sample's porosity.
