Document Type and Number:
Japanese Patent JP7220794
Kind Code:
B2
Abstract:
Zirconia/titanium oxide/cerium oxide doped rare earth tantalum/niobate RETa/NbO4 ceramic powder and preparation method therefor. The Zirconia/titanium oxide/cerium oxide doped rare earth tantalum/niobate RETa/NbO4 ceramic powder has a chemical general formula RE1-x(Ta/Nb)1-x(Zr/Ce/Ti)2xO4, 01, 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/NbO4 ceramic powder which satisfies the requirements of an APS technology for ceramic powder.
