Abstract

A series of samples of the piezoelectric compositions  with calcined at temperature of  for have been synthesized by the solid-solutions method. The compositions are crystallized as  structure under the preparation conditions. The structural changes and thermal stability as a function of the ratio were investigated by using X-ray powder diffraction XRD and differential thermal analysis DTA. The study of XRD spectrum showed that the solid solution formation between FePO4 and AlPO4, takes place by incorporation of Fe3+ ions into the AlPO4 structure. This solid solution formation is accompanied with a phase transformation to phase at the temperatures (920 – 940)  for the ratios  respectively. The changes in the chemical bondslengths and their effects on the structure of these compositions were studied using different methods of spectral analysis; the spectra of  ,  , and  as a function of . Thermal stability and phase transition temperature of the two samples prepared has been found to be higher for the ratios  than for each of the  and .
