| 摘 要： | 本文以Ｓｎ作熔剂，以石墨作坩埚，在一个半密闭的石墨容器内，用“熔渣－金属”化学平衡法测定了含挥发性组分Ｂ２Ｏ３的ＣａＯ－Ｂ２Ｏ３二元系中ＣａＯ的活度；用α函数积分法计算了Ｂ２Ｏ３的活度．实验结果与文献报道的利用相图和生成自由能计算得到的数据相符．

| Abstract: | The activity of CaO in the CaO-B2O3 slag containing volatile component B2O3 has been measured in a partially sealed graphite container in equilibrium between the slag and melt, and the activity of B2O3 has been calculated by integrating Gibbs-Duhem equation. The experimental results are in good agreement with the previous data derived from the phase diagram and free energies of formation. |
