一种A2B2O7型高熵氧化物陶瓷及其制备方法和应用
本发明涉及一种A2B2O7型高熵氧化物陶瓷及其制备方法和应用，属于核废物固化技术领域。本发明A2B2O7型高熵氧化物陶瓷材料为(Gd0.2Sm0.2Dy0.2Er0.2Yb0.2)2Ti2O7高熵陶瓷基材料，其中，A位点金属元素Gd、Sm、Dy、Er、Yb为等原子比。采用高能球磨及放电等离子烧结法制备。所制备的(Gd0.2Sm0.2Dy0.2Er0.2Yb0.2)2Ti2O7高熵陶瓷材料为稳定的单相组织、成分分布均匀，具有高的致密度、良好的力学性能，优异的耐辐照性能，可以满足高放废物固化材料的使用需求。
The invention relates to A2B2O7 type high-entropy oxide ceramic as well as a preparation method and application thereof, and belongs to the technical field of nuclear waste solidification. The A2B2O7 type high-entropy oxide ceramic material is a (Gd < 0.2 > Sm < 0.2 > Dy < 0.2 > Er < 0.2 > Yb < 0.2 >) < 2 > Ti2O7 high-entropy ceramic-based material, and metal elements Gd, Sm, Dy, Er and Yb at the site A are equal in atomic ratio. The material is prepared by adopting a high-energy ball milling and spark plasma sintering method. The prepared (Gd0. 2Sm0. 2Dy0. 2Er0. 2Yb0. 2) 2Ti2O7 high-entropy ceramic material is a stable single-phase structure, is uniform in component distribution, has high density, good mechanical properties and excellent radiation resistance, and can meet the use requirements of high-level waste curing materials.
