几种二元熔盐作用浓度计算模型初探

张鉴

金属学报

按照正负离子未分开的条件分别对含固溶体、共晶体和复杂化合物的二元熔盐制定了作用浓度计算模型,计算结果与实测活度符合;按照正负离子分开的条件制定的计算模型,则未取得符合实际的结果,证明熔盐中正负离子的确是未分开的,原因是多数熔盐中缺乏介电物质.

CALCULATING MODELS OF MASS ACTION CONCENTRATIONS FOR MATTES (Cu_2S-FeS-SnS)INVOLVING EUTECTIC

金属学报(英文版)

Based on the facts that cations and anions of molten salts and binary basic oxide solid solutions do not separate from each other as well as that the electric conductivities of mattes are greater than that of salts and basic oxide solid solutions, the calculating models of mass action concentrations for binary and ternary mattes involving eutectic have been formulated. The results of calculation agree well with the values measured;this in turn shows that the calculating models can reftect the structural characteristics of the mattes concerned.
