Lithium ceramic tritium breeding agent with curved-surface pore channel structure and preparation method of lithium ceramic tritium breeding agent
The invention belongs to the related technical field of porous ceramic material preparation, and discloses a lithium ceramic tritium breeding agent with a curved surface pore channel structure and a preparation method of the lithium ceramic tritium breeding agent. The lithium ceramic tritium breeding agent is of a periodic extremely-small-curved-surface porous structure, the diameter of a pore channel ranges from 0.5 mm to 2 mm, and the porosity ranges from 15% to 35%. The preparation method comprises the following steps: S1, preparing a pore passage sacrifice model; S2, preparing ceramic slurry; S3, carrying out slip casting; S4, carrying out drying and low-temperature degreasing; and S5, sintering to obtain the lithium ceramic tritium breeding agent with the curved surface pore channel structure. According to the invention, the structure of the tritium value-added agent is changed from a straight-through structure to a curved surface structure, from a disordered structure to a regular structure, and from an uncontrollable performance to an adjustable performance, and the tritium value-added agent has a regular, uniform and communicated curved surface hole channel structure in geometric space; and the problems that a porous lithium ceramic tritium breeding agent cannot disperse load stress and is low in mechanical and thermal stability and overall mechanical strength are solved.
本发明属于多孔陶瓷材料制备相关技术领域，并公开了一种曲面孔道结构的锂陶瓷氚增殖剂及其制备方法。该锂陶瓷氚增殖剂呈周期性的极小曲面多孔结构，其中，孔道直径为0.5mm～2mm，孔隙率为15％～35％。制备方法包括下列步骤：S1孔道牺牲模型的制备；S2陶瓷浆料的制备；S3注浆成型；S4干燥和低温脱脂；S5烧结，以此获得曲面孔道结构的锂陶瓷氚增殖剂。通过本发明，实现氚增值剂的结构从直通到曲面，结构从无序到规律，性能从不可控到可调节，在几何空间上具有规则、均一、连通的曲面孔道结构，解决多孔锂陶瓷氚增殖剂无法实现对负载应力的分散和力学、热学稳定性及整体的机械强度低的问题。
