Abstract
The present disclosure relates to the technical field of ceramic powder preparation, and discloses a zirconia/titania/cerium oxide doped rare earth tantalum/niobate RETa/NbOceramic powder and a preparation method thereof. A general chemical formula of the ceramic powder is RE(Ta/Nb)(Zr/Ce/Ti)O, 0<x<1, the crystal structure of the ceramic powder is orthorhombic, the lattice space group of the ceramic powder is C222, the particle size of the ceramic powder ranges from 10 to 70 μm, and particles of the ceramic powder are spherical. During preparation, the raw materials are ball-milled before a high temperature solid phase reaction, then mixed with a solvent and an organic binder to obtain a slurry C, then centrifuged and atomized to obtain dry pellets, and finally sintered to obtain a zirconia/titanium oxide/cerium oxide doped rare earth tantalum/niobate RETa/NbOceramic powder, which satisfies the requirements of APS technology for ceramic powders.
