Formation of phases during the solid state synthesis of the barium-modified NBT solid solutions, with substitutions of zirconium and tin ions for titanium are investigated. The synthesis is a multi-step process which is accompanied by the formation of a number of intermediate phases (depending on the solid solution composition and the synthesis temperature). Single phase solid solutions have been manufactured when the sintering temperature was increased to 1000-1100 C. An increase of the concentration of the substituting ions results in a linear increase in the size of the crystal cell. As a consequence the reduction of the tolerance factor and an increase of the stability of the antiferroelectric phase with respect to the ferroelectric one take place.
