Abstract

Silicate-based glass that devitrifies on heating to form ferroelectric lead titanate has been developed. The potential for use as sintering aid in PbO-based electroceramics has been evaluated by studying the densification of PbTiO3 (PT) with increasing wt% addition of glass powder. As the wt% glass content increased, the density increased, the maximum and room temperature relative permittivity decreased and there was also a decrease in Tc and the c/a ratio. The decrease in Tc is believed to be due to increased clamping from neighbouring grains as the density of the PT increases. The decrease in maximum and room temperature relative permittivity is related to the presence of secondary phases.
