High-entropy oxide ceramic capable of improving crack resistance and preparation method of high-entropy oxide ceramic
The embodiment of the invention discloses high-entropy oxide ceramic with improved crack resistance and a preparation method of the high-entropy oxide ceramic. The high-entropy oxide ceramic comprises the following components: oxide ceramic powder, nano silica sol, a binder, a dispersing agent and a solvent. The nano-silica sol has the advantages of uniform particles, no toxicity, no pollution, large specific surface area, high reaction activity, high adsorption capacity, high bonding performance and the like, and the application finds that the nano-silica sol is applied to the high-entropy oxide ceramic, can be closely distributed in a ceramic matrix and can be well combined with other components, so that the high-entropy oxide ceramic can be prepared. The stability of the overall structure of the high-entropy oxide ceramic is enhanced, the generation of microcracks is reduced, and the crack resistance is improved; in the preparation process of the high-entropy oxide ceramic, slurry is prepared through mixing and stirring, then the slurry is formed by using a 3D direct-writing printing technology, and finally the high-entropy oxide ceramic with excellent crack resistance is obtained through the steps of drying, degreasing, sintering and the like.
