Based on the thermodynamically self-consistent analysis and optimization of three sub-binary systems ofthe ternary system PrCl_3-CaCl_2-MgCl_2,the thermodynamics of this ternary system has been studied.UsingHillert model and taking MgCl_2 as an asymmetric component,the PrCl_3-CaCl_2-MgCl_2 phase diagram hasbeen calculated.The agreement between calculated and measured compositions and temperatures at deflectingpoints on liquidus is good.The system is a simple eutectic one with a eutectic point at 26.0mol% PrCl_3,41.5mol% CaCl_2,32.5mol% MgCl_2;560℃(calculated)and 26.0mol% PrCl_3,39.4mol% CaCl_2,34.6mol%MgCl_2;546℃(measured),respectively. 相似文献

The cathodic electrode process of Y~(3+) ions on the Mo electrode in the LiCl-KCl molten salt withYCl_3(3wt%) in the temperature range of 450~530℃ has been investigated using cyclic voltammetry andchronopotentiometry.The convolution technique has been applied to the treatment of cyclic voltammogram.Theresults show that the reduction mechanism of Y~(3+) ion is Y~(3+)+3e=Y,a simple one-step process.The cathodicprocess is very close to a reversible process under lower scanning rates,and is diffusion-controlled.The cathodicproduct is an insoluble product. 相似文献

轻/重水堆中子辐照氢区熔硅退火特性的比较 总被引:2,自引:0,他引:2
用电阻率测量、金相观察以及红外光谱等方法分别研究了氢区熔硅单晶在轻水反应堆和重水反应堆进行中子辐照后的退火特性。电阻率退火曲线表明,两种中子辐照样品都存在氢致施主。随着退火温度由低到高,轻水堆辐照样品存在一个导电类型由p型到n型的转型过程,而且在这种转型过程中,有一个明显的“周边滞后”现象。在重水堆辐照样品中,热处理缺陷表现为氢致Φ型缺陷(大麻坑),而在轻水堆辐照样品中,热处理缺陷表现为尺寸小得多的氢沉淀。红外光谱测量结果表明,重水堆中子辐照的样品经短时退火后观察不到氧沉淀,而在轻水堆辐照样品中存在吸收峰在1230cm-1附近的氧沉淀。 相似文献

本文简要阐明了相图计算的原理和主要数值计算方法。相图计算的关键之一是确定体系中各相的过剩摩尔自由能,因而侧重评述了预示熔盐溶液相的过剩摩尔自由能的理论模型和几何方法及其进展。指出了计算的意义和局限性,阐明了理论计算相图与实验测定相结合是构筑熔盐相图的最佳方法。 相似文献
