摘　　要：研究了Na2SO4/SiO2复合储能材料的工艺性能.进行了成型压力、烧成温度和保温时间3因素3水平L9(33)正交实验.分析了这些因素对储能材料的致密度与高温强度的影响,从中获得了致密度和高温强度最佳时的工艺参数.对储能材料的蓄热性能进行了初步研究,结果表明Na2SO4/SiO2复合储能材料的蓄热密度是显热陶瓷蓄热料的2.7倍.Processing technology of Na2SO4/SiO2 composite energy storage material is studied. Three factors, i.e. molding pressure, sintering temperature and heat - retaining time are selected for the orthogonal - design experiment L9 （3^3 ）. The effects of these factors on the density and high temperature strength are analysed with SEM. The optimal process parameters are obtained. Thermal energy storage performances are investigated. Results showed that the thermal energy storage density is 2.7 times to sensible heat ceramic materials.
