| Oxide ceramics are the most widely used and most productive ceramic materials with high mechanical strength, electrical insulation performance, chemical stability, etc. They are widely used in aerospace, military defense, industrial production and other fields. However, the brittleness of oxide ceramics seriously restricts its wider application in cutting-edge fields. In order to solve this problem, scholars both domestically and internationally have begun to explore the solid state phase transition method for preparing fine nanostructured oxide composite ceramics in recent decades. They constructed the nano/submicron/micron scale structure of nanocomposite oxide ceramics by solid state phase transformation to improve their mechanical properties. This paper systematically reviews the effects of solid state phase transition method on the microstructure and properties of nanocomposite oxide ceramics, aiming to elucidate their related principles and processes, and provide references for the preparation of high-performance nanocomposite oxide ceramics. |
