The review begins with a brief introduction to the properties of zirconia and alumina ceramics. The different methods for combining zirconia and alumina ceramics are then discussed. The effects of sintering conditions on the tetragonal phase stability, densification, mechanical properties, evolution of microstructural and grain size of the alumina toughened zirconia are also presented. Previous studies have reached a consensus on the influence of sintering temperature, sintering time, and alumina content on the properties of ATZ composites. Generally, elevating sintering temperatures and prolonging sintering times result in heightened densities and improved mechanical properties. However, the impact of alumina content is less straightforward, as divergent findings exist, some studies indicate that higher alumina contents correspond to diminished properties, while others reveal no significant effect. Additionally, the sintering method emerges as a pivotal determinant impacting the properties of ATZ ceramics. Notably, microwave sintering has demonstrated superiority over traditional methods, yielding heightened properties. Optimal density and mechanical properties of ATZ composites can be achieved through meticulous control of sintering conditions. By comprehending the factors influencing ATZ, the production of ATZ composites tailored to specific applications becomes attainable, offering the prospect of desired properties. � 2023 The Authors Final 2024-10-14T03:17:22Z 2024-10-14T03:17:22Z 2023 Review 10.1016/j.mtcomm.2023.106964 2-s2.0-85169976304 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85169976304&doi=10.1016%2fj.mtcomm.2023.106964&partnerID=40&md5=18767d198a911600066b0dfd4d054273 https://irepository.uniten.edu.my/handle/123456789/33878 37 106964 All Open Access Hybrid Gold Open Access Elsevier Ltd Scopus
