抄録

Some iron ores were reduced by CO gas in a modified scanning electron microscope equipped with a temperature and gas control; iron precipitates during the reduction were directly observed. Growing mechanism of such precipitates was discussed on their growth in vertical and horizontal directions: the vertical growth is caused by precipitation of supersaturated iron ions under an iron nucleus, which is consequently pushed out toward a free space; while the horizontal one by precipitation of iron ions at a three-phase boundary of precipitated iron, wustite and gas where they were produced. The typical fibrous iron was represented as the result of predominant vertical growth. Very long, fine and dense fibrous iron which appeared in a sulfur-bearing atmosphere was speculated to be attributed to inhibition of the sulfur from the three-phase boundary reaction.
