用摆杯粘度计测量了In-Se-Te三元系不相容液体在偏晶至约1200K温度范围内的剪切粘度。结果表明，三元In80SexTe20−x(0⩽x⩽20at.%)体系可视为一组准二元In-(Se/Te)合金，其浓度接近临界浓度。在In含量不变的情况下，Se/Te比的变化会改变共存液体的性质，并影响双节温度。对描述临界点附近粘度行为特性的临界参数进行了估算。提出了基于相变动力学理论的分相区粘度分析方法。将计算结果与非混溶介质溶液和金属熔体的现有数据进行了比较。
Shear viscosity measurements were carried out for a liquid immiscible ternary system In–Se–Te in a temperature range from the monotectic to about 1200K using an oscillating-cup viscometer. It was revealed that the ternary In80SexTe20−x(0⩽x⩽20 at.%) system may be considered as a set of quasibinary In–(Se/Te) alloys of almost critical concentrations. A variation of the Se to Te ratio at constant content of In changes the properties of coexisting liquids and affects the binodal temperature. The critical parameters describing the peculiarities of viscosity behavior in the vicinity of the critical point are evaluated. The analysis based on the dynamic theory of phase transitions for viscosity in the phase separation region is proposed. The results are compared with available data for immiscible dielectric solutions and metallic melts.
