“…A spongy structure of reduction products predetermines satisfactory gas exchange during heat treatment in the zone of reaction. That is, as noted in papers [6,12], of essential importance are the chemical reactions involving a gaseous An increase in the degree of reduction of the scale led to a decrease in the intensity of manifestation of iron oxides with the detection of a-Fe (Fig. 3).…”

“…The importance of participation of the gas phase of carbon oxides during reduction processes in the system Fe-Cr-O-C is specified in [12]. Authors of papers [13,14] noted a possibility of the progress of parallel reduction and the formation of Cr 3 C 2 , Cr 7 C 3 , Cr 23 C 6 , at temperatures 1,273-1,773 K. We should emphasize the course of carbide formation and the unavoidable presence of carbides in reducing carbon-thermal processes.…”

“…In addition, the relatively high temperature and the low partial pressure p O of atomic oxygen over the MeO-C mixture facilitate the forma tion of the unstable suboxide C 3 O 2 . This may play the important role of supplying elementary carbon the surface of the metal oxides [35].…”

“…The importance of carbon monoxide decomposition in the regenerative processes in the Fe-Cr-O-C system was noted in work [13]. In the reactions between Cr 2 O 3 and C, the first stage is the dissociation of oxides with the release of atomic and molecular oxygen and the formation of carbon oxides.…”

“…The possibility to form a solid solution of carbon and doping elements in α-Fe and Fe 3 C and (Fe, Cr) 7 C 3 carbides was established. Also important are the results reported in work [13] involving the decomposition of carbon oxides during reduction processes in the Fe-Cr-O-C system. But at the same time, there are the disregarded notions about the influence of ore impurities on the patterns of the reduction of oxide chromium-containing raw materials.…”
