GROWTH OF LEAD CALCIUM TITANATE SINGLE-CRYSTALS AND THEIR CHARACTERIZATION

Single crystals of perovskite ferroelectric solid solutions Pb1-xCaxTi O3 with different Ca content were grown from high temperature solution s by Remeika's technique using KF as a Aux. The crystals were nearly e quidimensional in morphology and slightly bigger size crystals were ob tained for 10 mole% of Ca content. Two dimensional layer growth patter ns have been found on the (100) surface. Marked influence of Ca substi tution on lattice parameter values and curie temperature has been foun d using X-ray diffraction and differential scanning calorimetry studie s.
