Abstract

Pb(1-x)CaxZr0.52Ti0.48O3 bulk ceramic compositions where x=0-0.1 in steps of 0.02 are prepared by solid state reaction method and sol-gel technique. A comparative study on the samples is conducted using XRD and Raman Spectroscopy in order to see the effect of processing conditions. XRD peaks are indexed as per monoclinic phase. In both the series of samples, volume shrinkage of the unit cell is observed in calcium modified samples when compared with unmodified samples. It is interesting to note that the samples derived from solid state reaction exhibit pseudo tetragonal structure while sol-gel derived samples show pseudo rhombohedral structure of their monoclinic unit cell. Similar inference has been made via Raman spectroscopy studies on the studied ceramic compositions prepared via two methods. Raman spectroscopy also reveals the possibility that calcium substitutes for lead
