A2B2O7 type high-entropy ceramic powder, gamma ray shielding composite coating and preparation method
The invention discloses A2B2O7 type high-entropy ceramic powder, a gamma ray shielding composite coating and a preparation method, and belongs to the field of radiation shielding materials. The invention aims to solve the problem that secondary radiation brings harm to people and the environment and even exceeds primary radiation. The A2B2O7 type high-entropy ceramic powder is applied to the field of radiation shielding as a functional filler, an element A is composed of five or more of Sc, Y, La, Nd, Eu, Gd, Dy, Er, Yb and Lu, an element B is one or a combination of Zr, Sn and Hf, and the A2B2O7 type high-entropy ceramic powder can be prepared through a high-temperature solid phase method, a sol-gel method and a coprecipitation and hydrothermal treatment method. The invention is applied to radiation-proof clothes in work, medical treatment and the protection field required in the nuclear industry.
本发明公开了一种A2B2O7型高熵陶瓷粉末和屏蔽伽马射线的复合涂层及制备方法，属于辐射屏蔽材料领域。本发明要解决二次辐射给人和环境带来的危害甚至超过了初级辐射的问题。本发明将A2B2O7型高熵陶瓷粉末作为功能填料应用于辐射屏蔽领域，其中元素A是Sc、Y、La、Nd、Eu、Gd、Dy、Er、Yb和Lu中的五种或者五种以上的元素组成，元素B是Zr、Sn和Hf中的一种或其中几种的组合，A2B2O7型高熵陶瓷粉末可通过高温固相法、溶胶凝胶法、共沉淀和水热处理法制备。本发明应用于工作中的防辐射服、医疗方面及核工业中所需的防护领域。
