Recently, more and more attention is paid on applications of molten chlorides in concentrated solar power （CSP） plants as high-temperature thermal energy storage （TES） and heat transfer fluid （HTF） materials due to their high thermal stability limits and low prices, compared to the commercial TES/HTF materials in CSP- nitrate salt mixtures. A higher TES/HTF operating temperature leads to higher efficiency of thermal to electrical energy conversion of the power block in CSP, however causes additional challenges, particularly increased corrosiveness of metallic alloys used as contain- ers and structural materials. Thus, it is essential to study corrosion behaviors and mechanisms of metallic alloys in molten chlorides at operating temperatures （500-800℃） for realizing the commercial application of molten chlorides in CSE The results of studies on hot corrosion of metallic alloys in molten chlorides are reviewed to understand their corrosion behaviors and mechanisms under various conditions （e.g., temperature, atmosphere）. Emphasis has also been given on salt purification to reduce corrosive impurities in molten chlorides and development of electrochemical techniques to in-situ monitor corrosive impurities in molten chlorides, in order to efficiently control corrosion rates of metallic alloys in molten chlorides to meet the requirements of industrial applications.

MgCl_(2)–NaCl–KCl salts mixture shows great potential as a high-temperature(>700°C)thermal energy storage material in next-generation concentrated solar power *** Mg into molten MgCl_(2)–NaCl–KCl salt as a corrosion inhibitor is one of the most effective and cost-effective methods to mitigate the molten salt corrosion of commercial Fe–Cr–Ni ***,it is found in this work that both stainless steel 310 and Incoloy 800H samples were severely corroded after 500 h immersion test at 700°C when the alloy samples directly contacted with the over-added Mg in the liquid *** corrosion attack is different from the classical impurity-driven corrosion in molten chloride salts found in previous *** analysis indicates that Ni preferentially leaches out of alloy matrix due to the tendency to form MgNi_(2)/Mg_(2)Ni *** Ni-depletion leads to the formation of a porous corrosion layer on both alloys,with the thickness around 204μm(stainless steel 310)and 1300μm(Incoloy 800H),*** results suggest that direct contact of liquid Mg with Ni-containing alloys should be avoided during using Mg as a corrosion inhibitor for MgCl_(2)–NaCl–KCl or other chlorides for high temperature heat storage and transfer.

以粉煤灰、石灰石和无水碳酸钠为原料,通过烧结法制备了以钙长石、钙铁辉石和霞石为晶相的复合晶相微晶玻璃。借助差热分析、X射线衍射及扫描电子显微镜研究了晶化温度(850～1100℃)对微晶玻璃析晶行为、显微形貌和性能的影响。结果表明:随晶化温度的升高钙长石和霞石晶相的含量先增加后降低,钙铁辉石晶相含量逐渐增加,同时微晶玻璃中晶体形态逐渐由球形微晶发育成柱状,最后长成片状;晶化温度的升高有利于微晶玻璃的烧结致密化,1 050℃时微晶玻璃的线收缩率和体积密度达到最大,分别为17.04%和2.76 g/cm3,吸水率最小,为0.01%。过高的晶化温度(1100℃)会降低其致密程度。

基于我国面临CO_(2)减排与磷石膏资源化利用的巨大压力,本文提出助剂循环使用的CO_(2)矿化与磷石膏资源化利用过程耦合的学术思想,立题以磷石膏为原料,研究醋酸钠体系下氨水强化磷石膏浸出液矿化CO_(2)联产高纯CaCO_(3)的反应过程。实验过程中系统讨论了不同工艺条件对磷石膏中Ca^(2+)的浸出及浸出液矿化CO_(2)反应效能的影响,并系统表征了反应条件对矿化产物晶粒尺寸、结构与形貌的影响。结果表明:低温常压条件下1t磷石膏可以矿化吸收208kg的CO_(2),同时联产472kg纯度为99.63%的球形球霰石。通过调节矿化反应条件可有效调控矿化产物的晶粒尺寸;提高反应温度和延长反应时间有利于亚稳态的球霰石向热力学更稳定的文石和方解石转化。实验过程中实现了醋酸钠的循环利用与回收。本文为磷石膏的资源化利用与高纯CaCO_(3)的制备提供了新的思路。
