Zirconium oxide-based composite powder, zirconium oxide pre-sintered body and preparation method thereof, zirconium oxide sintered body and preparation method and application thereof
The invention provides zirconium oxide-based composite powder, a zirconium oxide pre-sintered body and a preparation method thereof, and a zirconium oxide sintered body and a preparation method and application thereof, and relates to the technical field of composite materials. The zirconium oxide-based composite powder provided by the invention comprises yttrium oxide powder, aluminum oxide powder and zirconium oxide powder, the specific surface area of the zirconia-based composite powder is 7.5-9g/m < 2 >; the particle size D50 of the zirconium oxide based composite powder is 180 to 250 nm. When the zirconia-based composite powder provided by the invention is used for preparing a zirconia sintered body, the zirconia sintered body with relatively high strength and density can be obtained only by sintering a zirconia pre-sintered body for less than or equal to 30 minutes, so that the production efficiency is greatly improved.
本发明提供了一种氧化锆基复合粉体、氧化锆预烧体及其制备方法、氧化锆烧结体及其制备方法和应用，涉及复合材料技术领域。本发明提供的氧化锆基复合粉体包括氧化钇粉末、氧化铝粉末和氧化锆粉末；所述氧化锆基复合粉体的比表面积为7.5～9g/m2；所述氧化锆基复合粉体的粒度D50为180～250nm。采用本发明提供的氧化锆基复合粉体制备氧化锆烧结体，仅需要将氧化锆预烧体进行≤30min的烧结时间，就可以得到强度和密度均较高的氧化锆烧结体，大大提高了生产效率。
