内容記述 | Our previous reports described the determination of activity of SiO_2 and Al_2O_3 in the slag of CaO-SiO_2-Al_2O_3 system by using the e. m. f. method of double cell. The present study investigated the effect of MgO on the activity of SiO_2 and Al_2O_3. From the experimental results it was found that at a constant concentration of Al_2O_3, activity coefficient of SiO_2, γ SiO_2 increased as substitution of MgO for CaO increased. With the addition of MgO, the activity of silica approached Raoult's law. At a constant MgO concentration, the amphoteric nature of Al_2O_3 was clarified as in CaO-SiO_2Al_2O_3 system. Concerning the effect of MgO on the activity of Al_2O_3, an intimate relation exists between αAl_2O_5 and basicity, that is, by chosing the basicity as N_<CaO+MgO>/N_<SiO_2>, a relationship could be found between log αAl_2O_3 and basicity which corresponded to the results obtained in the slag of CaO-SiO_2-Al_2O_3 System. The above facts show the behaviour of MgO which acts as a base. | |||||||||
