核聚变产氚锂陶瓷制造研究进展
Research progress in production of tritium breeding lithium ceramics for nuclear fusion
摘要
Abstract
Lithium ceramics(e.g.,Li4SiO4,Li2TiO3),as core tritium breeder materials,possess high lithium density,excellent thermal stability,and irradiation resistance.Traditional manufacturing methods such as extrusion-spheronization and melt-spraying face challenges including poor particle size uniformity,low crush load,and structural simplicity.As an advanced manufacturing technology,3D printing offers innovative solutions for the precision forming of lithium-based tritium breeding ceramics in nuclear fusion reactors.Vat photopolymerization-based 3D printing enables the integrated fabrication of complex tritium breeding units(e.g.,honeycomb structures,porous frameworks),significantly improving structural precision,mechanical properties,and tritium release efficiency.This article systematically reviews the material properties,powder preparation processes,and limitations of conventional forming techniques for lithium ceramics,with a focus on the technical advantages and application prospects of vat photopolymerization 3D printing in achieving"structure-property synergy"manufacturing,as well as the multi-precursor-based generative shaping and material-forming method.Finally,future research directions are also proposed to address current technical challenges.关键词
