Bismuth ferrite (BiFeO3) was obtained by a combustion reaction staring from two precursors systems, namely Fe(NO3)3 · 9H2O–Bi5O(OH)9(NO3)4 · 9H2O–glycine/urea with different metal nitrate/fuel molar ratios. The precursors’ thermal behavior is

Two bismuth ferrite potential precursors systems, namely Fe(NO3)3·9H2O-Bi(NO3)3·9H2O-glycine/urea with different metal nitrate/organic compound molar ratios have been investigated in order to evaluate their suitability as BiFeO3 precursors. The pre
