摘　　要：为探究玄武岩作为熔融盐斜温层混合蓄热单罐系统中储热填充介质的可行性,实验对玄武岩与熔融硝酸盐的相容性进行了研究,并采用X射线衍射分析、岩相分析和热重-差示扫描量热分析等方法对其进行了表征。结果表明,玄武岩与硝酸盐相容性较好,能够满足储热填充介质的使用需求。In order to research the feasibility of using basalt as packing medium in the one tank thermocline hybrid storage system with molten-salt,the compatibility between basalt and molten nitrate was studied. X-ray diffraction a- nalysis, petrographic analysis and thermogravimetry and different scanning calorimetry（TG-DSC） were used to characterize. The results show that basalt has good compatibility with molten nitrate,so that it can be used as packing medium.
