| titleOfInvention | A2B2O7 type rare earth tantalate ceramic and preparation method thereof |
| abstract | The invention relates to the technical field of thermal barrier coatings, and particularly discloses an A2B2O7 type rare earth tantalate ceramic and a preparation method thereof, according to RE 2 MTaO 7 Structural formula (II) RE 2 O 3 And M 2 O 3 Respectively dissolving in concentrated nitric acid to react, adjusting pH to not less than 1.5, and adding TaOCl 3 Dropwise adding the solution, continuously stirring, adding ammonia water to stabilize the pH value of the system to 9-10, continuously stirring in a water bath environment, washing the precipitate with deionized water until the pH value is 7, drying the obtained filter cake in an oven, and sieving for later use; placing the powder in a graphite grinding tool, performing spark plasma sintering in a sintering furnace, and annealing and decarbonizing the sintered sample to obtain compact RE 2 MTaO 7 Block of a material having low thermal conductivity and high hardnessDegree and fracture toughness. |
