摘要
本文利用含NbFe液与Nb_2O_5-MnO-SiO_2渣之间平衡,在1828K温度下应用固体电解质浓差电池方法测定了Fe液中氧的活度,从而计算出渣中Nb_2O_5及MnO的活度,并绘制了Nb_2O_5-MnO-SiO_2三元系的等α_(Nb_2O_5)和等α_(MnO)图。
Equilibrium between liquid Fe containing Nb with Nb_2O_5-MnO-SiO_2slag was investigated at 1828 K, the solid electrolyte oxygen concentration cell be-ing used to measure the activity of oxygen in the metal bath. The activity of Nb_2O_5and MnO in the slag was evaluated, accompanied with an iso-activity diagram ofα_(Nb_2O_5) and α_(MnO) in Nb_2O_5-MnO-SiO_2 slag.
