The study of producing metal based oxides has become increasingly interesting because of several specific features which make them extremely attractive for various uses, e.g.: catalysts, pigments, magnetic records, sensors, etc. In the present paper we report the synthesis of various iron, copper and nickel oxides by the IR laser processing of different salts. X ray diffraction technique was used in order to characterize the reaction problems. An analysis of the differences between these oxides and those obtained from the same salt by thermal means is presented. It was found that the oxides obtained by laser processing show specific characters concerning the crystallinity and chemical composition.
