Research progress in zirconia toughened alumina ceramics
Year: 2025
Type: article
Abstract: Zirconia toughened alumina （ZTA） ceramics exhibit excellent mechanical properties compared to single-phase Al2O3 and ZrO2 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.
