摘　　要：针对赤泥、油页岩利用率极低的现状,基于热蚀变原理,对赤泥、油页岩进行了蚀变处理。借助XRD、IR等一系列微观测试分析工具,研究了蚀变混合物料的物质组成、结构特性以及表面形貌。结果表明:混合物料在700℃,煅烧2h时,活性明显提高。As to the low utility of red mud and oil shale, the red mud and oil shale are treated using the hydrothermal alteration principle. By using several testing methods, such as XRD, IR, the material composition, structural characteristic and surface pattern are studied. The results indicate that the activity of the material is best when calcined in 700℃ for two hours.
