| titleOfInvention | High-entropy carbide ultra-high temperature ceramic powder and preparation method thereof |
| abstract | The invention provides a high-entropy carbide ultra-high temperature ceramic powder and a preparation method thereof. The molecular formula of the ceramic powder is (M1 x1 M2 x2 ...Mn xn )C, and M is Zr, Ti, Hf, V, Nb At least four of , Ta, Mo or W have a single face-centered cubic structure and are a single-phase solid solution. Said method: at least four metal oxides and carbon powder are made into cathode, and molten salt electrolysis is used to obtain nanometer ceramic powder. The invention can simultaneously realize mixed electrodeoxidation, in-situ carbonization and solid solution of various metal oxides in the electrolysis process, and has the advantages of short process flow, low raw material price, low synthesis temperature, low equipment requirements, simple process, easy industrialization and It has the advantages of high economic value; it can provide an economical and feasible new route for the preparation of high-quality high-entropy carbide nanopowder; it can also be used as a semi-finished product for aerospace components, coating materials and special functional ceramics. |
