Preparation method of high-porosity uranium carbide-based porous ceramic material
The invention discloses a preparation method of a high-porosity uranium carbide-based porous ceramic material, relates to the technical field of preparation of foamed ceramic materials, and aims to solve the problems that an existing uranium carbide porous ceramic material is relatively low in porosity and difficult in microstructure regulation and control, and radioactive powder pollution possibly exists in the operation process. The method comprises the following steps: 1) preparing a precursor solution; (2) dipping the porous template in the precursor solution, then drying in the air, and circulating the steps for 1-6 times to obtain a porous material blank; and 3) carrying out high-temperature ceramization treatment on the porous material green body to obtain the uranium carbide-based porous ceramic material. According to the preparation method of the uranium carbide-based porous ceramic material, the problem of radioactive dust pollution can be avoided, the experimental process is simple, and operation and control are convenient. The prepared uranium carbide-based porous ceramic material is high in porosity and adjustable in microstructure, and can be applied to the technical field of online isotope separation.
