Wpływ technologii wytwarzania na stopień rozmycia ferroelektrycznych przemian fazowych w ceramice typu PZT

Abstract

Admixed solid solutions of the PZT type were used as a material to test the infuence of ceramic material production technologies on the degree of diffuse phase transition. It has been shown in the work that two main factors decide about the degree of diffuse phase transition in PZT, that is composition fluctuations in the ceramic micro-volumes and heterogeneity in the distribution of defects and mechanical stresses. Technological conditions have a great in fluence on the two factors above. While comparing the degree of diffuse phase transition for different ceramic materials of the PZT type it is important to use the same criterion.
