Preparation and identification of nano-perovskite LaCrO۳ from the thermal decomposition of an heterobimetallic complex using microwave radiation

In this research, the heterobimetallic complex La[Cr(C۲O۴)۳].۱۰H۲O was prepared by mixing an equimolar aqueous solution of K۳[Cr(C۲O۴)۳] complex and La(NO۳)۳ solution and as a precursor for the preparation of nanoperovskite LaCrO۳, it was exposed to microwave radiation. The possible changes made in the structure of the decomposition product of this aberrant complex and the formation of new mineral phases was identified using X-ray diffraction (XRD) and FT-IR spectroscopy. The microstructure and morphology of the product were examined by scanning electron microscope (SEM) and determination of chemical composition and purity by EDX analysis.
