Based on the columbite route proposed by Swartz and Shrout, pure perovskite 75Pb(Zn 1/3 Nb 2/3 )O 3 –10PbTiO 3 –15BaTiO 3 solid solution ceramics are synthesized by the modified two-step method. The ZnNb 2 O 6 and PbO by the molar ratio 1:3.05 were ball-milled and then pre-reacted at 660°C for 1–2h. This pre-reacted mixture was wet mixed with...
