Resumo
Sr(Ti,Nd)O(3) was synthesized in order to evaluate the influence of the amount of neodymium on the thermal and structural properties of SrTiO(3). The synthesis was carried out using the polymeric precursor method. A small mass gain was observed for the SrTiO(3) and SrTi(0.98)Nd(0.02)O(3) samples accompanied by an exothermic peak in the DTA curves. Other steps at higher temperatures are assigned to the combustion of the organic material and carbonate. Elimination of defects by previous calcination of the precursors is responsible by the short and long range ordering of the perovskite. Cubic phase was obtained for undoped and doped SrTiO(3).
