抄録

In order to investigate the mechanisms of sulfurization of iron oxide such as the formation of iron sulfide dust during smelting reduction of iron ore, wustite samples synthesized to some specific compositions as well as magnetite and metallic iron were sulfurized mainly at 900°C in a controlled sulfur partial pressure. The degree of sulfurization reaction was thermogravimetrically monitored for each experiment and several samples were subject to XRD, SEM and EDX analyses. The rate controlling step of sulfurization reaction has been considered to be the diffusion of iron in the FeS layer produced, and its diffusion coefficient at 900°C is estimated to be 4.7-7.0×10^-9cm²/s.
