摘要
This article uses Sn as the metal flux and CaF2-CaO as the reference slag to experimentally measure the activity of CaO at T = 1773 similar to 1873 K. The effects of different w(Al2O3) and temperature(T) on CaO activity were investigated. The results are as follows: when w(MgO) = 6%, R(w(CaO)/w(SiO2)) = 1.20, w(Al2O3) = 12%, 14%, 16% and 18%, with the increase of w(Al2O3), the activity and activity coefficient of CaO in slag gradually decrease; with the increase of temperature (T), the activity and activity coefficient of CaO in slag gradually increase; the activity coefficient of Ca in Sn decrease with increasing temperature.
