为了更好地了解铁水除磷过程，应用溶液模型推导了硅酸二钙和磷酸三钙固溶体的吉布斯自由能。本文所建立的规则溶液模型及确定的参数，给出的各组分的活度与文献数据和相图在热力学上一致。
For a better understanding of phosphorus removal from hot metal, the Gibbs free energies of solid solutions between di-calcium silicate and tri-calcium phosphate were derived through applications of solutions models. The regular solution model with the parameters determined in this study gave the activities of the components thermodynamically consistent with the literature data and the phase diagrams.
