Synthesis and electrical properties of Pb(Mg<inf>1/3</inf>Nb<inf>2/3</inf>)O<inf>3</inf>-PbTiO<inf>3</inf>ceramics

Ceramic compositions of a combination between lead magnesium niobate, Pb(Mg1/3Nb2/3)O3, and lead titanate, PbTiO3, were fabricated by using Mg4Nb2O9precursor technique. Their electrical properties with respect to temperature and frequency were examined and the effect of sintering conditions on phase...
