| Abstract | ||
| The lead titanate PbTiO3 was prepared by solid state reaction method . In this method ,the mixture of (PbO : TiO2) compounds in mole ratio [1:1] was calcined at 900 оC for 2 hr. The crystallisation and growth of tetragonal PbTiO3 phase ( c/a =1.039) were investigated by using XRD technique. The dielectric properties of PbTiO3 were reported, in which the dielectric constant of PbTiO3 increases with increasing temperature in tetragonal phase to reach maximum value at curie temperature (486 оC) ,then decreases with increasing temperature in cubic phase. The loss factor increases with increasing temperature in different ratios The electric resistivity of PbTiO3 decreases with increasing temperature. | ||
