Studies on the nitriding and reduction in the nanocrystalline iron-ammonia-hydrogen system
Com. Fe catalyst for NH3 synthesis was nitrided with NH3-H-2 mixts. at 350 degrees C. The nitriding resulted in formation of stable Fe(N), Fe4N and Fe2-3N phases. After redn., the area of the Fe2-3N phase was extended.
