摘要
在1500℃下以金属锡作熔剂,石墨作还原剂,采用“熔渣—金属锡”化学平衡法,测定了含氧化钛高炉渣中氧化钙的活度。并讨论了渣中氧化钙的活度和活度系数随氧化钛的浓度及氧化镁浓度的变化规律。同时导出了适用于此种渣系的碱度公式。
The activity of CaO in blast furnace slag containing titanium oxide has been determined at 1500℃ by using 'molten slag-liquid tin' chemical equilibrium method with tin as solvent and graphite as deoxidizer. The relationships between activity and activity coefficient of CaO on the one hand and both concentrations of titanium oxide and magnesium oxide on the other have been discussed. A basicity formula for this slag system has been given.
