Pb—Bi和Tl—Bi熔体的作用浓度计算模型

CALCULATING MODEL OF MASS ACTION CONCENTRATIONS FOR Pb—Bi AND Ti—Bi MELTS

根据含化合物金属熔体结构的共存理论和Pb—Bi与Tl—Bi熔体活度值对拉乌尔定律负偏差的对称性推导了它们的作用浓度计算模型。计算结果与实际是符合的,从而证明所得模型是反映以上两熔体的结构特点的。

According to the coexistence theory of metallic melts structure involving compound formation and the symmetric negative deviation of activities of Pb-Bi and Tl-Bi melts from Raoult's law, a calculating model of mass action concentratios for these alloys has been derived. Good agreement between the calculated results and measured values shows that this model can exactly reflect the structural reality of these melts.
