摘　　要：熔融盐相变储热材料具有潜热大、储能密度高、过冷度小、热稳定性好、成本低等优点,广泛应用于太阳能热利用的储热介质。在对熔融盐相变储热材料进行分类的基础上,综述了国内外对碳酸盐、氯化盐和硝酸盐等储热材料在热物性和腐蚀性方面的研究现状。针对熔融盐储热材料导热率低的问题,详述了以膨胀石墨、金属、陶瓷、陶土等为基体材料、熔融盐为附体材料的高导热率复合材料制备方面的研究进展。最后展望了熔融盐相变储热材料的研究趋势。It is an introduction of advantage of the molten salt phase change material for storing heat, such as large latent heat, small sub cooling, high thermal capacity, good thermal stability, low cost etc. It is widely applied in solar energy heat storage medium, on the basis of the molten salt phase change material for storing heat being classified, reviewed the present situation of domestic and foreign research about Carbonate, Chlorate, Nitrate, such as the thermal physical and the corrosive. To the question of the molten salt phase change material for storing heat conductivity low, the progress of high thermal conductivity composite material preparation with expanded gra-phite,metals, ceramics and clay for matrix material, the molten salt for incarhate material is summarized. At last, the tendency of the molten salt phase change material for storing heat is prospected.
