Lead magnesium niobate, Pb(Mg1/3Nb2/3)O3(PMN) was produced using the columbite method and the effect of milling on the formation of the perovskite phase of Pb(Mg1/3Nb2/3)O3was investigated. Columbite, MgNb2O6, was ball milled with PbO for 24, 48, 72 and 96 h before calcining at 650-750 °C for 2 h. T...

Columbite, MgNb2O6, was ball milled with PbO for 24, 48, 72 and 96 h before calcining at 650-750 °C for 2 h.
