摘　　要：氧化锆增韧氧化铝(zirconia toughened alumina,ZTA)陶瓷与单相Al_(2)O_(3)和ZrO_(2)陶瓷相比具有优异的力学性能,在电子、生物医疗、半导体等高端工业领域显示出更广阔的应用前景。本文结合ZTA陶瓷的增韧机制,梳理并总结了近期国内外关于ZTA陶瓷的粉体制备、烧结方法和第三相引入等三方面的研究进展,重点分析了利用多种烧结技术和制备工艺在ZTA陶瓷中引入第三相的作用,最后指出粉体的纳米化、先进烧结技术的精细控制以及探索第三相对微观组织的调控是未来研究的重点方向。Zirconia toughened alumina(ZTA)ceramics exhibit excellent mechanical properties compared to single-phase Al_(2)O_(3)and ZrO_(2)ceramics,demonstrating broader application prospects in high-end industrial fields such as electronics,biomedicine,and semiconductors.This paper reviews the toughening mechanism of ZTA ceramics and summarizes recent research progress,both domestic and international,on three aspects:powder preparation,sintering methods,and the introduction of the third phase.It focuses on analyzing the role of third-phase incorporation in ZTA ceramics through the use of various sintering techniques and processing methods.Finally,it points out that the nano-structuring of powders,fine control of advanced sintering techniques,and exploration of the microstructure through third-phase modulation are key directions for future research.
