Abstract

The dielectric properties of (Ba0.2Pb0.8)TiO3 prepared by several methods related to dispersion have been studied. The sol-gel derived specimens without dispersion have lower density, and lower dielectric constant at the Curie temperature. The sol-gel specimens derived from a well-dispersed suspension with pH 11 and 13, and 2% PMMA show higher dielectric constant at the Curie temperature, and higher density, because the grains grow homogeneously in the well-dispersed system. The sol-gel derived specimens have a higher Curie temperature than that of calcined mixed oxides and molten salt synthesis derived specimens.
