| titleOfInvention | Cerium double-doped lanthanum zirconate nano ceramic powder and preparation method thereof |
| abstract | The invention provides cerium double-doped lanthanum zirconate nano ceramic powder and a preparation method thereof, wherein the preparation method comprises the following steps: preparing a mixed solution of cerium salt, zirconium salt and lanthanum salt, and mixing the mixed solution with a precipitator to obtain hydroxide colloid; centrifuging and washing the hydroxide colloid to obtain a precipitate; filter-pressing the precipitate to obtain semi-solid hydroxide gel; uniformly mixing the semi-solid hydroxide gel with a dispersing agent, and then drying to obtain a solid product; and calcining the solid product to obtain the cerium double-doped lanthanum zirconate nano ceramic powder. The invention also provides cerium double-doped lanthanum zirconate nano ceramic powder obtained by the preparation method, and the structural formula of the nano ceramic powder is as follows: (La) 1‑x Ce x ) 2 (Zr 0.7 Ce 0.3 ) 2 O 7 Wherein x is more than or equal to 0.05 and less than or equal to 0.2. The preparation method provided by the invention has less process flow, and the nano ceramic powder obtained by the preparation method has higher thermal expansion coefficient. |
