Synthesis and electrical properties of Pb(Mg1/3Nb2/3)O3-PbTiO3 ceramics

Ceramic compositions of a combination between lead magnesium niobate, Pb(Mg1/3Nb2/3)O3, and lead titanate, PbTiO3, were fabricated by using Mg4Nb2O9 precursor technique. Their electrical properties with respect to temperature and frequency were examined and the effect of sintering conditions on phas...
