A new technique for synthesis of the CuN and its structural indexing

We report the synthesis of the polycrystalline CuN phase via a diffusion reaction between copper and nitrogen under extreme conditions. Herein, the solid-state diffusion mechanism for the synthesis of the CuN phase was analyzed. Structural indexing of the new phase was confirmed using the X-ray diffraction technique. Synthesis of the above CuN phase applying this novel technique is an inexpensive method for the industrial production of the material. The microstructure of the above solid was investigated under a high-resolution scanning electron microscope.
