摘　　要：采用一定的制备工艺将金属基(泡沫镍)与K2CO3,Li2CO3,Na2CO3,LiOH和NaOH等熔融盐在一定温度下进行复合,得到一种新型复合蓄热材料。用扫描电镜,X-射线以及差热-差重分析等手段对复合蓄热材料的结构与性能进行研究,测试结果表明该复合蓄热材料达到了预期的结果;进一步讨论了复合时间和复合材料中熔融盐含有率关系以及复合温度和蓄热密度之间的关系。In this paper, a series of new heat storage materials were prepared by combining porous metal nickel base and some kinds of molten salts at certain temperature. Structures and properties of these materials were studied by SEM, X-ray diffraction and TO-DTA techniques. The experimental results reveal that the combining action proceeded fully between the metal matrix and the molten salts. And the effects of composite time on percentage of phase-change material and composite temperature on the heat storage density were discussed.
