摘要
In this paper, a new molten salt/ceramic composite phase change thermal storage material was prepared by sol-gel method and powder compacting method. The surface of molten salt particles was encapsulated with SiO2 or TiO2 by sol-gel method, then the molten salt particles were combined with MgO to prepare composite phase change thermal storage materials. By this method, the density of the composite increased by 8.74%, the thermal conductivity increased by 16.27%, after high-temperature heat. The decline of the heat loss rate was only 2.67%.
