Multi-element doped zirconium oxide light-cured ceramic slurry as well as preparation method and application thereof
The invention belongs to the technical field of additive manufacturing and forming, and particularly relates to multi-element zirconium oxide-doped light-cured ceramic slurry as well as a preparation method and application of the multi-element zirconium oxide-doped light-cured ceramic slurry. The 3D printing slurry obtained by the traditional zirconia ceramic slurry preparation process has the defects of single ceramic powder type, low solid content, poorer dispersion stability and printing self-leveling property and the like. The mechanical property of a 3D printing ceramic part is poorer than that of zirconia ceramic prepared by a traditional forming process. In order to solve the problems, various oxide powders are uniformly dispersed in the ceramic slurry by utilizing modified doped ceramic powder and adopting a composite modification-multi-element co-doping method, so that the rheological property and the printing self-leveling property of the ceramic slurry are greatly improved, and the application range of the ceramic slurry is widened. The solid content of the powder is increased, meanwhile, uniform doping and mixing of multi-element oxide powder are achieved, the mechanical property is remarkably improved, and the method has huge potential application value in the medical clinical field and the military aviation and aerospace field.
本发明属于增材制造成型技术领域，特别是涉及一种多元掺杂氧化锆光固化陶瓷浆料及其制备方法和应用。传统氧化锆陶瓷浆料制备工艺得到的3D打印浆料，存在陶瓷粉体类型单一、固含量低，且分散稳定性和打印自流平性较差等缺点；3D打印陶瓷制件的力学性能较传统成型工艺制备的氧化锆陶瓷差。为解决上述问题，本发明利用改性掺杂陶瓷粉体，采用“复合改性‑多元素共掺杂”方法，实现多种氧化物粉体在陶瓷浆料中的均匀分散，极大地提升了陶瓷浆料的流变性能和打印自流平性，在提升粉体固含量同时实现了多元氧化物粉体的均匀掺杂和混合，显著提高了力学性能，在医疗临床领域、军工航空航天领域具有巨大潜在应用价值。
