DOIAbstract
A new method for growing single crystals of ferroelectric PbTiO<SUB>3</SUB> is described. A mixture of TiO<SUB>2</SUB>, Pb<SUB>3</SUB>O<SUB>4</SUB> and KF in the ratio 1 : 2.5 : 6.5 is taken in a platinum crucible and heated to a temperature of about 900°C to 950°C for about 20 hours. The melt is then slowly cooled to room temperature. Flat plates of PbTiO<SUB>3</SUB> crystals are grown by this method. The dielectric properties of these single crystals of PbTiO<SUB>3</SUB> are studied in the temperature range 0-600°C. The Curie temperature has been found to be 495°C with a Curie constant of the order of 1.1 X 10<SUP>5</SUP>. The conductivity of these samples shows an anomalous variation at and near the Curie temperature
