of a spinel phase. It was also observed that the heating rate employed in TG–DTA analysis significantly effects peak temperatures. The effects of high heating rate give rise to the reactions to occur at higher temperatures. It was found that

increasing calcination temperature, the peak intensities to PbTiO 3 became stronger and all reflections could be assigned to PbTiO 3 . There was no evidence for phase separation. The above results are in good agreement with the TG–DTA analysis result. The
