Abstract
CaxSr1-xTiO3 (CxST; x=0.2 and 0.4) powders were elaborated by conventional solid state reaction. Structural and electrical properties were influenced by the Ca2+ doping content. Structural and microstructures properties of the obtained powders were conducted by X-ray diffraction and scanning electron microscopy. The powder were pressed to eight tons into cylindrical pellets and sintered at 1300°C for 3h. The electrical and dielectric properties were measured by two-probe method using HP 4192 Analyzer. The refinement of results showed that the samples were crystallized in the tetragonal with I4/mcm space group. The highest conductivity was shown for C0.2ST sample which equal to 1.21 x 10-4 S.cm-1 at 600 °C. The electrical and dielectric parameters were plotted and discussed as a function of temperature and frequency. These Ca doped perovskite ceramics materials can be used as possible candidate for a wide range of applications in various devices.
