摘要：
Zirconia/titanium oxide/cerium oxide doped rare earth tantalum/niobate RETa/NbO 4 ceramic powder and preparation method therefor. The Zirconia/titanium oxide/cerium oxide doped rare earth tantalum/niobate RETa/NbO 4 ceramic powder has a chemical general formula RE 1-x (Ta/Nb) 1-x (Zr/Ce/Ti) 2x O 4 , 0 1 , the partical size is 10-70 µm, and the ceramic powder is spherical. During preparation, a raw material is ball-milled, reacts by adopting a high-temperature solid phase method, and then mixes with a solvent and an organic adhesive to obtain slurry C; centrifugal atomization is performed to obtain dry granules, and then the dry granules are sintered to obtain the Zirconia/titanium oxide/cerium oxide doped rare earth tantalum/niobate RETa/NbO 4 ceramic powder which satisfies the requirements of an APS technology for ceramic powder.
