Description
UC or CeC2 were converted into U2N3 or CeN by the use of NH3 or an N2/H2 gas mixture. A stream of NH3 works not only as a nitriding agent but also as a carbon clearing agent due to its high nitriding and hydriding activities. When the carbide is converted into nitride, carbon is liberated. Some experiments were performed in order to examine the role of the carbon activity of carbon materials (amorphous carbon or graphite) in the formation of CH4. (orig.)
