Combustion Synthesis of Perovskites from Solid Organometallic Glycine-Based Precursors
New organometallic glycine-based complex precursors of perovskites (ABO3, A2BO4) have been synthesized and their
combustion has been carried out in two regimes: the volume combustion synthesis (VCS) and the self-propagating hightemperature synthesis (SHS). Phase composition of the combustion products has been studied by a set of physicochemical methods (IR, XRD, TEM HR and etc.). It was shown that the composition of perovskite precursors and the applied combustion regime are the most significant factors determining the process of their decomposition. It was found that in the SHS regime the perovskite content in the combustion product was as high as 90% without the additional energy-consuming calcination. The observed phase homogeneity and high crystallinity degree of the resulting perovskites may indicate that a higher combustion temperature has been reached in the SHS regime.
