High-entropy oxide ceramic as well as preparation method and application thereof
The embodiment of the invention discloses high-entropy oxide ceramic as well as a preparation method and application thereof. The high-entropy oxide ceramic comprises the following components in parts by weight: 60-75 parts of oxide ceramic powder; 10 to 15 parts of lignin; 2 to 5 parts of graphene; 5 to 8 parts of tris (hydroxymethyl) aminomethane; and 15 to 20 parts of a solvent. In the embodiment of the invention, lignin, graphene and trihydroxymethyl aminomethane are added into oxide ceramic powder; wherein the graphene and the tris (hydroxymethyl) aminomethane can act together to enhance the grain boundary binding force, enhance the density of a ceramic matrix, and improve the hardness and the bending strength of the ceramic; meanwhile, lignin with a three-dimensional network structure can act together with trihydroxymethyl aminomethane, and can participate in optimizing the microstructure of the ceramic, so that the generation of microcracks is reduced, and the crack resistance is improved. Therefore, the high-entropy oxide ceramic provided by the embodiment of the invention has better impact resistance.
