采用溶胶-凝胶法制备了3种不同钡锶物质的量比的Ba1-xSrxAl2Si2O8 (BSAS)体系粉体材料,其钡、锶物质的量比分别为1∶0、0.75∶0.25、0∶1.将烧结得到的BSAS块体材料表面喷涂(8.5±0.2)mg/cm2的Na2SO4后,置于1000℃空气环境中进行熔盐腐蚀实验,研究其抗熔盐腐蚀性能.根据样品质量随腐蚀时间的变化,结合X射线衍射(XRD)和扫描电镜形貌分析(SEM)等结果,揭示其抗熔盐腐蚀机理.结果表明,B0.75 S0.25AS腐蚀100h后质量变化最小,XRD分析其成分未发生明显变化,说明B0.75S0.25AS在1000℃时的抗熔盐腐蚀性能优于其它物质的量比的BSAS材料.
