This work describes powdered materials belonging to the Aurivillius oxide family (Bi{sub 2}O{sub 2})(A{sub n{minus}1}B{sub n}O{sub 3n+1}), for n = 2 and n = 3, and provides an approach for understanding the structural evolution with composition. Five kinds of solid solutions, Bi{sub 2{minus}x}Pb{sub x}Sr{sub 2}Nb{sub 2}TiO{sub 12{minus}x/2}, Bi{sub 2{minus}y}Pb{sub y}Sr{sub 1{minus}y}La{sub y}Nb{sub 2}O{sub 9}, Bi{sub 2{minus}z}Pb{sub z}SrNb{sub 2{minus}z}Mo{sub z}O{sub 9}, Bi{sub 2{minus}u}Pb{sub u}Sr{sub 2{minus}u}La{sub u}Nb{sub 2}TiO{sub 12}, and Bi{sub 2{minus}v}Pb{sub v}Sr{sub 2}Nb{sub 2+v}Ti{sub 1{minus}v}O{sub 12} were studied. The new material Bi{sub 2}Sr{sub 2}Nb{sub 2}TiO{sub 12}, as well as its structural evolution when Pb{sup 2+} is placed in Bi sites and the loss of charge is compensated by doping in A or B sites, is described. A study of ferropiezoelectric behavior in Bi{sub 2}Sr{sub 2}Nb{sub 2}TiO{sub 12} and Bi{sub 1.5}Pb{sub 0.5}Sr{sub 2}Nb{sub 2}TiO{sub 11.75} samples is discussed.
