摘要：

Variation of tolerance factor was observed with doping of Sr and Bi at A and B sites respectively and independently in BaTiO3 compound. Stability of NBT based compositions is varied with the substitution of Ba content in A-site and alters with the concentration. Combining with the electronegativity difference and octahedral factor of ABO(3) structure, regularities governing the formation and the stability of perovskite type compounds are discussed. According to the results of BST and BBT series both dopants are reduce the tolerance factor and increase the distortion within the lattice of ABO(3)-type perovskite, the experience tolerance factor value and experience electronegativity difference value to form stable perovskite compound were obtained.
