Thermal properties of Sr0,3 Ba0,7Ti1-yZryO3 ferroelectric ceramics: Dependence on sample’s porosity
The thermal properties of Sr0,3Ba0,7Ti1-yZryO3 (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 linear...

| Sumario: | The thermal properties of Sr0,3Ba0,7Ti1-yZryO3 (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. |
