项目摘要

Activities of liquid indium-base and thallium-base alloys are important not only from the standpoint of their behavior as impurities during nonferrous smelting but also of the physical chemistry of liquid alloys. Therefore, a study of activities of the liquid indium-typical metal and thallium-typical metal alloys has been carried out by the emf measurements using the Galvanic cells with zirconia and fused-salt electrolytes.The results obtained are summarized as follows ;(1) The activities of both components at 1000 K and 1200 K, 750 K and 1000 K in the liquid Sb-Tl and Bi-Tl alloys, respectively, indicate negative deviations from Raoult's law over the whole concentration ranges. The activities of both components for the Bi-Tl alloys exhibit moderately greater negative deviations than those for the Sb-Tl alloys.(2) Activities of indium and bismuth at 900 K and 1200 K in the liquid Bi-In alloys showed negative deviations from Raoult's law almost whole concentration range. The activities … More of both components for the Sb-In alloys exhibit more negative deviations than those for the Bi-In alloy. Deviations of the activities of indium and copper from Raoult's law at 1050 K and 1250 K are positive for the indium-rich region and are negative for the copper-rich side of the liquid Cu-In alloys. Activities of liquid alloys composed of IB metals (Cu, Ag and Au) and indium have been discussed in terms of the alloy solution theory of Engel.(3) The activities of indium and thallium at 1000 K and 1200 K, 900 K and 950 K in the liquid Te-In and Te-Tl alloys, respectively, show large negative deviations from Raoult's law in the tellurium-rich regions and remarkable negative to positive deviations from ideality in the indium-rich and thallium-rich regions. The activities of tellurium at the same temperatures exhibits negative deviations from Raoult's law over the whole concentration ranges.(4) The activities of both components for all the alloys mentioned above approach the ideal lines with increasing temperature within the whole composition ranges.

液体依赖碱和硫碱合金的活性不仅从其行为的角度来看很重要，在非有产性冶炼过程中，而且是液体合金的物理化学性质的重要性。因此，通过使用带有氧化锆和融合的盐盐电解质的电动型细胞进行的EMF测量进行了对液体依赖型金属和硫型金属合金的活性研究。所获得的结果如下所示。分别表明在整个集中度范围内脱离拉乌尔特的法律。 BI-TL合金的两种成分的活性比SB-TL合金的负面偏离更大。（2）液体双合金中900 K和1200 K的inimin和需要次的活性显示出与Raoult法律法律的负面差异几乎全浓度。这些活动……SB-IN合金的两种组件都比BI-IN合金的差异更多。在1050 K和1250 K时，IS和铜与Raoult定律的活动的偏差对富含二氮的区域呈阳性，并且对液体Cu-In合金的铜一侧呈阴性。 Activities of liquid alloys composed of IB metals (Cu, Ag and Au) and indium have been discussed in terms of the alloy solution theory of Engel.(3) The activities of indium and thallium at 1000 K and 1200 K, 900 K and 950 K in the liquid Te-In and Te-Tl alloys, respectively, show large negative departures from Raoult's law in the tellurium-rich regions and remarkable negative to positive departures from ideal in the富含ICH和硫富的区域。在相同温度下的泰瑞尔人的活性在整个浓度范围内表现出与拉乌尔特定律的负面不同。（4）上述所有合金的两个组件的活性接近理想线，随着整个组成范围内的温度升高。较少的
