Abstract :
Phase T,x-diagram of the Pb1-xCaxTiO3 (0⩽x⩽0.62) solid solution system has been constructed in the range from room temperature to 770 K using data of single crystal optical studies and X-ray microanalysis. Besides the typical for PbTiO 3 ferroelectric tetragonal and paraelectric cubic phases, two ferro- and non-ferroelectric ones having the pseudomonoclinic unit cell distortions also as two additional tetragonal phases, at least one of which is confidently non-ferroelectric, have been found and their exact stability limits have been determined
