Abstract
Measurements of the elastic (Young's) modulus, mechanical losses and d.c. e lectrical conductivity as a function of the temperature in Aurivillius type structure ferroelectric ceramics have been performed. The results suggest that the anomalies appearing in macroscopic complex elastic modulus and ele ctrical conductivity near the temperature of 300 degrees C, do not correspo nd to a ferro- paraelectric or ferro-ferroelectric phase transition. These anomalies could be caused by a change in the defect structure coming from u nstable Bi3+ cation. (C) 1999 Elsevier Science Limited. All rights reserved .
