Abstract

This study was carried out to investigate the effects of Bismuth (Bi+3) and Yttrium (y(+3)) on the dielectric and piezoelectric properties of Lead Magnesium Niobate-Lead Titanate (PMN-PT) compositional system. The ceramic powders were produced by thermal synthesis using a modified mixed oxide technique. The sintering parameters were optimized for developing piezoelectric ceramics with enhanced piezoelectric strain coefficients.
