Effect of calcination conditions on phase formation and particle size of lead nickel niobate powders synthesized by using Ni4Nb2O9 precursor

Effect of calcination conditions on phase formation and particle size of lead nickel niobate powders synthesized by using Ni4Nb2O9 precursor

An approach to synthesize lead nickel niobate, Pb(Ni1/3Nb2/3)O3 or PNN, powders with a modified two-stage mixed oxide synthetic route has been developed. Novel intermediate phase of nickel diniobate (Ni4Nb2O9) was employed as a B-site precursor, with the formation of the PNN phase investigated as a...
