This article presents a simple and fast method to synthesize metal fluorides such as FeF₂, CoF₂, ZnF₂,LaF₃, YF₃, SrF₂, and metal oxide Fe₂O₃ having different morphologies. The synthesis is carried out in anionic liquid solvent using a domestic microwave oven. The products are characterized with the help ofan X-ray diffraction method. The different morphologies of the products are studied with the help of ahigh-resolution transmission electron microscope and a high-resolution scanning electron microscope.The change in the oxidation state of the reactant Fe(III) to the product Fe(II) is confirmed throughMössbauer studies. The presence of carbon and its application as a reducing agent is illustrated by Ramanspectroscopy.
