| titleOfInvention | A kind of gadolinium-nickel co-doped magnesium-based lanthanum hexaaluminate ceramic and its preparation method |
| abstract | The invention relates to a preparation method of gadolinium-nickel co-doped magnesium-based lanthanum hexaaluminate ceramics, belonging to the field of preparation and application of inorganic non-metallic materials. The present invention is obtained by doping Gd to La site and Ni to Mg site at the same time, according to the chemical formula La 1-x Gd x Mg 1-x Ni x Al 11 O 19 for batching, wherein 0.1≤X≤0.5; firstly, the mixed metal salt is prepared Solution, then add complexing agent and dispersant, and then undergo complexation, esterification, and drying to obtain precursor powder, and then calcined at 1000-1200 ° C for 3-6 hours to obtain the original powder, and press the original powder. It is sintered at 1400-1600°C to obtain gadolinium-nickel co-doped magnesium-based lanthanum hexaaluminate ceramics. The preparation process of the invention is simple, the shape of the ceramic block is regular, and the thermophysical performance is good, and the invention can be used as a candidate material for the thermal barrier coating of an aerospace engine. |
