Effect of niobate B-site precursors on phase formation and particle size of lead nickel niobate powders
A perovskite phase of Pb(Ni1/3Nb2/3)O3or PNN powders has been synthesized by a rapid vibro-milling technique. Both NiNb2O6and Ni4Nb2O9have been employed as nickel niobate precursors, with the formation of the PNN phase investigated as a function of calcination conditions by DTA and XRD techniques. M...
