Boron nitride/high-entropy ceramic oxide and composite coating for shielding neutrons and gamma rays and preparation method of boron nitride/high-entropy ceramic oxide and composite coating
The invention discloses a boron nitride/high-entropy ceramic oxide and composite coating for shielding neutrons and gamma rays and a preparation method of the boron nitride/high-entropy ceramic oxide and composite coating, and belongs to the field of radiation protection. The invention aims to solve the problem that simultaneous shielding of neutrons and gamma rays is difficult to realize by a single material. In the A2B2O7 type high-entropy ceramic powder, an element A is composed of five or more elements of Gd, Er, Sm, La, Ce, Eu and Dy, and an element B is Hf; the surface of the high-entropy ceramic powder is coated with boron nitride to form a composite filler, and the composite filler and the resin form a composite coating. The method is applied to the fields of spacecrafts, radioactive medical treatment, nuclear reactors and the like.
本发明公开了一种屏蔽中子和γ射线的氮化硼/高熵陶瓷氧化物和复合涂层及其制备方法,属于防辐射领域。本发明要解决单一材料较难实现中子和γ射线的同时屏蔽的问题。本发明的A2B2O7型高熵陶瓷粉末中元素A是Gd、Er、Sm、La、Ce、Eu、Dy中的五种或者五种以上的元素组成,元素B为Hf;高熵陶瓷粉末表面包裹有氮化硼构成复合填料,所述复合填料和树脂形成复合涂层。本发明应用于航天器、放射性医疗、核反应堆等领域。
