The electric properties and specially influence of defects on electrical conductivity are presented for modified PZT ceramics. The spectr of energie for oxides perovskite type A[2+]B[4+]O[3] is shown. The influence of ...

Selected problems of the methodics of measuring the orientation polarization (P[r]) of ceramic ferroelectrics were discussed on the example of the ceramics PLZT 9/65/35. These ceramics can be easily switched as their ...

Temperature dependence of the electric permeability and of the spontaneous polarization were studied. A systematic change in chemical composition was observed during the growth process. The ageing process dependence on ...

The temperature changes of electric conductivity and of electric permittivity were investigated for the $NaNbO_3$ and $NaNbO_3$ + /0,1%, 0,2%, 0,25%, 0,3%, 0,4%, 0,5% and 1% mol $La_2O_3$/ ceramics. Obtained data were ...
