Recovery voltage in ZnO ceramics

The paper presents short review of non-ohmic ceramics properties with respect to four energy conversion in the material bulk. Recovery voltage response is shown as phenomena that origins in that conversion. Modelling of ZnO ceramic sample in pre-breakdown area by means of linear dielectrics for the purpose of polarisation analysis is described. Recovery voltage responses of new and thermally aged samples are measured and differences in time domain are shown. Results are discussed. Streszczenie.
