Synopsis (1) Appropriate selection of nitrogen pontential and treating temperature pattern during the treatment enables saving of NH3 amount and shortening of treating time. (Fig. 17) dominant chemical reactions in the furnace chamber during the treatment and progress of the water gas reaction is slow.
