Effects of magnesium niobate precursor and calcination condition on phase formation and morphology of lead magnesium niobate powders
A perovskite phase of lead magnesium niobate, Pb(Mg1/3Nb2/3)O3or PMN, powders has been synthesized by a rapid vibro-milling technique. Both columbite MgNb2O6and corundum Mg4Nb2O9have been employed as magnesium niobate precursors, with the formation of the PMN phase investigated as a function of calc...
