Samarium-doped high-entropy aluminate ceramic material with garnet structure as well as preparation method and application of samarium-doped high-entropy aluminate ceramic material
The invention provides a samarium-doped high-entropy aluminate ceramic material with a garnet structure as well as a preparation method and application of the samarium-doped high-entropy aluminate ceramic material, the chemical structural general formula is Re3-xSmxAl5O12, Re comprises at least five trivalent rare earth elements, Sm is a doping ion, and the valence state is + 3, xlt; and 0.2 part. Besides, the preparation method is simple and easy to implement, the preparation method has the characteristics that the reaction sintering time of the material at high temperature is short, a large amount of energy consumed by maintaining a high temperature field for a long time can be saved, meanwhile, in the application and preparation process of the thermal barrier coating, the maintaining time of the thermal field of the thermal barrier coating is very short, and the thermal barrier coating can be applied to the thermal barrier coating. The conditions of the in-situ rapid reaction sintering preparation method are very close to those of industrial preparation, so that the properties of the thermal barrier coating material prepared by the method are more similar to those in actual production; in addition, the samarium-doped high-entropy garnet structure aluminate ceramic can obtain high density and high quantum efficiency through in-situ reaction sintering.
本发明提供了一种钐掺杂高熵石榴石结构铝酸盐陶瓷材料及其制备方法和应用，化学结构通式为Re3‑xSmxAl5O12，其中，Re包括至少5种三价稀土元素，Sm为掺杂离子，价态为+3价，x<0.2。另外，本发明的制备方法简单易实现，且该制备方法的特性就是材料在高温下的反应烧结时间较短，可以节省大量因长时间维持高的温度场而消耗的能源，同时在热障涂层的应用制备过程中，其热场的维持时间也是十分短暂的，那么这种原位快速反应烧结的制备方法与工业制备的条件十分接近，因此通过该方法制备出的热障涂层材料，其性质与实际生产中的更相似，另外原位的反应烧结可以使钐掺杂高熵石榴石结构铝酸盐陶瓷获得高的致密度和高的量子效率。
