• 要約等: application/pdf; The briquetted samples containing various amounts of Fe_2O_3,SiO_2 and CaO, were heated and sintered at 1,200℃ in the atmcsphere of air, or of mixed gas of 10%CO and 90%CO_2,or of mixed gas of 40%CO and 60%CO_2. The sintered samples were reduced with CO or H_2 gas at 900℃, and their reducibility, expressed as the relative constant of reduction rate, as determined from the reduction curve. The effect of the composition of samples and the sintering atmosphere on the reducibility, was established. Their porosities were also determined, and the relation between the reducibility and the porosity was established. The results were as follows : In the atmosphere of air, SiO_2 and CaO content had little effect on the reducibilty of iron exide, but the reducibility varied directly with the porosity. In the reducing atmosphere, SiO_2 added gave very had effect on the reducibility and even the addition of CaO for SiO_2 could not so much recover the reducibilty as injure it, if CaO was not enough for the amount of SiO_2 and there was no more direct relationship between the reducibility and the porosity, and the more reducing the atmosphere was, the more evident the tendency became.; 紀要類(bulletin); 807685 bytes
