High-entropy carbide ceramic for spent fuel shielding material and preparation method of high-entropy carbide ceramic
The invention belongs to the technical field of neutron and gamma radiation shielding materials, and particularly relates to high-entropy carbide ceramic for a spent fuel shielding material and a preparation method of the high-entropy carbide ceramic, the high-entropy carbide ceramic material is a (HfNbZrTaW) C5-xZrB2 high-entropy ceramic-based material, metal elements in (HfNbZrTaW) C5 are in an equal atomic ratio, and the mass percent of ZrB2 is 0-25w%. And preparing the designed (HfNbZrTaW) C (5-x) ZrB2 high-entropy ceramic-based material by adopting a high-energy ball milling and spark plasma sintering method. The prepared (HfNbZrTaW) C5 high-entropy ceramic material is a stable single-phase structure and is uniform in component distribution, and the high-entropy ceramic added with ZrB2 not only has the capability of shielding neutrons and gamma rays, but also has high thermal conductivity and good mechanical properties, and can meet the use requirements of spent fuel shielding.
本发明属于中子和γ辐射屏蔽材料技术领域，具体涉及乏燃料屏蔽材料用高熵碳化物陶瓷及其制备方法，本发明高熵碳化物陶瓷材料为(HfNbZrTaW)C5‑xZrB2高熵陶瓷基材料，其中，(HfNbZrTaW)C5中金属元素为等原子比为，ZrB2质量百分比为0～25w％。采用高能球磨及放电等离子烧结法，制备所设计(HfNbZrTaW)C5‑xZrB2高熵陶瓷基材料。所制备(HfNbZrTaW)C5高熵陶瓷材料为稳定的单相组织、成分分布均匀，添加ZrB2后的高熵基陶瓷不仅具有屏蔽中子和γ射线的能力，还具有高的热导率、良好的力学性能，能满足乏燃料屏蔽的使用需求。
