Abstract
Complex lead perovskites with nominal compositions Pb(B'B'')O3 ÄB': Mg, Zn, Ni, Co, Fe; B'': Nb, W, TaÜ are very important materials for dielectric and electrostrictive applications. The properties of such materials are strongly influenced by composition, synthesis procedure and sintering technology. In the present paper ceramics of lead magnesium niobate, lead nickel niobate and lead iron niobate were synthesized by different wet chemical and ceramics methods. Powders obtained by a modified ceramic procedure developed by H.C. Starck Goslar company characterized by high homogenity and reactivity. Sintered pellets of such powders shown very good dielectric properties.
