Properties of the elastic anomaly in SrBi2Nb2O9-based ceramics

A study was conducted on the effects of compositional modifications on the temperature coefficient of resonance frequency (TCF) in the disc planar vibration mode for the bismuth layer-structured compound SrBi2Nb2O9 (SBN)-based ceramics. The substitution of the strontium site by divalent and trivalent ions improved the TCF, accompanying the relaxation of elastic anomaly. The tolerance factor, t, was calculated for a pseudo cubic block to study the contribution of the structural factor to Curie temperature, T-C, and the temperature of elastic anomaly, T-ea, for each sample. T-ea showed no apparent tendency with t, whereas T-C increased as t decreased.
