Abstract
The formation of novel perovskite-type material via an EDTA (ethylenediaminetetraacetic acid)/citric acid complexing method was discussed. The procedure of the EDTA/citric acid complexing synthesis route is usually a low-temperature heating of the sol until gelation, followed by a heat treatment resulting in a pure perovskite powder. The nanometer scale location of the perovskite formation between the intermediates was verified by imaging using transmission electron microscopy (TEM) for ten different conglomerations, with homogeneous results. The inelastic scattered electrons can be resolved energy-dependently, and the resulting energy distribution with its characteristic ionization edges and energy-loss near-edge structures allows conclusions to be drawn about the element itself. TEM and EFTEM provide evidence that the perovskite structure was formed in a nanometer-scale solid-state reaction between the above mentioned intermediates and at their expense.
