dc.description.abstract | Mechanochemical synthesis o ers unique possibility of perovskite phase formation at
ambient conditions that is very attractive (simplifies production, allows strict stoichiometry control and
brings economic benefits). In this work the mechanochemical synthesis has been used for preparation
ofBa1xCaxTiO3 (0.2 x 0.3) powders from simple oxides. The 20 h milled powders have been
uniaxially pressed and sintered in order to get the ceramic samples. The sample morphologies
have been observed by scanning electron microscopy. Dielectric and impedance studies have
been performed on ceramics. The obtained results indicate that the two mechanism of doping
occurred. The first one is observed for the lower calcium concentration (below 0.3) and consists of the
introduction of calcium ion into the A site of the perovskite structure. The second one is observed for
the higher calcium concentration (equal 0.3). In this case the calcium ions partially occupies the B site
in the perovskite structure. Both cases have di erent influence on the final properties of the ceramics
because they induce di erent defects. | pl_PL |
