抄録	FeO compact including molten slag was reduced with H_2 at 1500 K, and the effect of the slag penetration in the reducibility was investigated. Two kinds of molten slag, which coexist with solid FeO, in FeO-SiO_2-CaO systems were used and the influence of the physical properties of molten slag, especially viscosity, on the reducibility was investigated. The penetrations of the molten slag with a low viscosity to the grain boundaries produce the spaces, which are useful as the pass of the reduction gas, in the interspaces between the grains. Then, the reduction rate of the FeO compact containing molten slag with a low viscosity is higher than that of the FeO compact containing molten slag with a high viscosity.
