Description
Summary: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. U radu se prikazuju rezultati koji se odnose na mogucnost sinteze dvostrukih perovskita Aurivilliusovih faza u sistemu BZN. Kriterijum zasnovan na elasticnom modelu strukture koriscen je pri oceni da li je favorizovano stvaranje slojevitog jedinjenja bizmuta u posmatranom sistemu. Izgleda da je temperatura odlucujuci faktor pri stvaranju Aurivillius-ove faze.
