摘　　要：复合相变蓄热材料目前广泛应用在太阳能和工业余热的回收方面,可解决在时间、空间上能源分配的失调,成为高温相变蓄热材料的最主要研究方向之一。我们以大同二电厂的垃圾粉煤灰为基体材料,预处理后与相变材料铝粉一起采用混合烧结法制出铝粉/粉煤灰基高温复合相变蓄热材料。采用XRD,SEM等测试分析技术对材料的组织结构与热物性能进行表征,结果表明,粉煤灰基复合相变蓄热材料成品各组分分布较均匀,具有十分优良的成形性和烧结性。The materials which have strongly heat storage capacity is called composite phase change heat storage materials. It can be applied in solar energy and recycling of industrial waste heat, for solving the problems in time, space, energy distribution imbalance.Now it has become one of the most important section of the high temperature phase change heat storage research. In this paper, high temperature composite phase change heat storage material is prepared by using mixed sintering method which use power plant waste fly ash as matrix material, and mixing together phase change materials, such as aluminium, making aluminium/fly ash. The influence of heat storage material is performed by XRD, SEM and other testing analysis technology. The results show that the distribution of the high temperature composite phase change heat storage materials of fly ash is very uniform, and it has very excellent formability and sintering performance.
