Abstract
Samples of CaO and CaO + MgO partially-stabilized zirconia (PSZ), solution treated at 1830° C and aged at 1400° C to produce a fine dispersion of tetragonal precipitates, were subjected to a.c. electrical measurements in the frequency range 10−3 to 106 Hz, at a temperature of 300° C. The component of resistivity due to the grain interiors, obtained from plots of complex resistivity, showed three stages of behaviour, attributed to equilibration, coarsening and finally transformation of a tetragonal precipitate into a more resistive monoclinic phase. A model of the electrical response of a dispersion of particles was used to estimate the conductivities of the constituent phases of the PSZ ceramic and to simulate the complex resistivity data obtained.
