摘要
本实验首次采用金属锗为溶剂，利用“渣—金”平衡法，在1733K下，测定了MgO—B2O3二元系熔渣中MgO的活度．并在以纯液态B2O3为标态下，用Gibbs－Duhem方程求得了该二元系熔渣中aB2O3实验结果令人满意．
In this experiment, the activity of MgO in MgO-B2O3 binary slag was determined at the temperature T= 1733K, by using a slag-metal equilibrium technique, firstadopting germanium as metal solvent. The activity of B2O3 was calculated analystically fromthe Gibbs -Duhem equation, taking pure liquid B2O3 as standard state. The result of theexperiment is satisfied.
