Abstract : The nature of the pyroelectric properties of the composite %Ca/Epikote 828 with 50/50 and 60/40 vol% was reported in the fifth interim report. The present report provides an account of the preparation of pure lead titanate (H) and calcium modified lead titanate (%Ca) by the Sol-Oel process. X-ray Spectroscopic Structural Analysis and Differential Scanning Calorimetric (DSC) studies of the ceramic grains produced by this technique were made and the results are given in this report. The sot-gel method for preparation of ferroelectric ceramics can offer many advantages over conventional processing techniques. Ceramics produced via the sol-gel method show high degrees of purity and homogeneity, can produce fme powders as well as being able to be formed into a variety of structures and they possess the ability to be processed at lower temperatures.
