In this paper the system NaCl CaCl2 SrCl2 and its binary systems were studied. Using a previously calculated phase diagram of the NaCl CaCl2 SrCl2 system as a basis, accurate measurements were carried out by MDTA with high sensitivity. It is a simple eutectic system with a eutectic point ...
CaCl2-NaF-CaF2-NaCl是互易盐系(reciprocal salt system),因为其具有化学反应:CaCl2 + 2NaF = CaF2 + 2NaCl,并且所有相都是电中性的,即2n(Ca2+) + n(Na+) = n(F-) + n(Cl-),其中n(i)表示离子i的摩尔数。 互易盐系液相线投影图的绘制有两种方法: (一)reciprocal相图模式"reciprocal diagram...
Investigations of the phase diagram of the NaCl-CaCl2-MgCl2-CaF2 reciprocal quaternary system have been performed by thermodynamic phase diagram calculations and cryoscopy. A limited concentration region of the system is used as a flux medium for liquid magnesium metal in connection with the casting ...
目前,常用的镁电解质体系主要有NaCl-KCl-MgCl2、CaCl2-NaCl-MgCl2、NaCl-CaCl2-KCl-MgCl2等[5-8]。 为了实现镁与氯气的分离和液镁的聚集及其与电解质的分离,电解需要在液镁熔点温度(651℃)以上进行,而此电解温度一般较电解质熔点高100~200℃,其会带来电解质挥发量的增加,大量的挥发物将随氯气进入氯压管线中,...
DETERMINATION OF PrCl_3-NaCl-LiCl PHASE DIAGRAM 利用DTA和X射线结构分析研究了NdCl3-LiCl二元体系相图和NdCl3-LiCl-NaCl三元体系液相限.发现NdCl3-LiCl体系相图属于简单低共熔型,低共熔点e3为28.5(wt%)LiCl,452℃.在... 张翊凤,郑朝贵,叶子浦 - 《化学学报》 被引量: 0发表: 1989年 PrCl3—CaCl2—MgCl...
The reversible EMF for the formation of MgCl2 in fused salts containing NaCl and CaCl2 was studied with a view to furthering the understanding of electrolytes of use in industrial magnesium electrolysis. Measurements were carried out in a cell with pure chlorine gas and Mg-Bi alloy as active ...
Thermodynamic evaluation and optimization of the LiCl-NaCl-KCl-RbCl-CsCl-MgCl2-CaCl2 system using the modified quasi-chemical model Arthur D. Pelton,Patrice Chartrand - 《Metallurgical & Materials Transactions A》 - 2001 - 被...
The partial molar enthalpy of water at 298 K is determined over a wide range of composition in the NaCl + CaCl2+ H2O system and the application of the McKay–Perring treatment to thermal measurements is examined. Unlike the water activity, which necessarily diminishes upon adding salts, the par...
CRYOGENIC RAMAN SPECTROSCOPIC STUDIES IN THE SYSTEM NaCl–CaCl2–H2O AND IMPLICATIONS FOR LOW TEMPERATURE PHASE BEHAVIOR IN AQUEOUS FLUID INCLUSIONS The character of Raman spectra in the O–H stretching region collected at low temperatures (~180°C) from fine-grained aggregates of ice and salt hydr...
Solubility isotherms of the ternary system (NH4Cl+CaCl2+H2O) were elaborately determined at T = (273.15 and 298.15) K by using the isothermal method. In... Ouyang Dong and Dewen Zeng and Hongyan Zhou and Haijun Han and Xia Yin and Yong Du - 《Calphad-computer Coupling of Phase Diagrams ...
