Abstract
In order to dope LaCuO3 by 57Fe Mössbauer probe, a novel high pressure oxidation process was developed. The orthorhombic phase La2Cu2O5:57Fe (2%) was used as a precursor due to its structure derived from the perovskite.The role of the structure of the precursor has been underlined through a comparison of the reaction routes from both structural forms (monoclinic and orthorhombic) of La2Cu2O5.This example illustrates the key role by the composition and the structure of the precursor for preparing novel materials.
