This paper presents results concerning the possible synthesis of double perovskite and Aurivillius phases in the BZN system. Acrystal chemical criterion based on an elastic model for the structure was used in order to determine if the formation of layered bismuth compounds is favoured in the above system. The tempeature seems to be the decisive factor influencing Aurivillius phase formation.
Keywords: synthesis, phase transition, thermal analysis, XRD.
