Untersuchungen zum Einfluß technologischer Parameter auf die dielektrischen Eigenschaften komplexer Bleiperowskite

Lead perovskites of the formula Pb(B'B'')O3 ÄB': Mg, Zn, Ni, Co, Fe; B'': Nb, W, TaÜ were synthesized by different wet chemical methods, the classical mixed oxide route and a modified ceramic procedure. The properties of the powders and consequently of the ceramics are strongly influenced by the synthesis method and the sintering technology. Powders obtained by the modified ceramic method developed by H.C.Starck Goslar company characterized by high surface area, high homogenity and reactivity. Sintered pellets of such powders shown very good dielectric properties.
