| titleOfInvention | Barium titanate doped modified lanthanum zirconate ceramic material and preparation method thereof |
| abstract | The invention relates to a barium titanate doped modified lanthanum zirconate ceramic material and a preparation method thereof. The ceramic material is synthesized by adopting a solid-phase reaction method (La) 1‑x Y x ) 2 (Zr 0.7 Ce 0.3 ) 2 O 7 Adding BaTiO into the precursor powder 3 And tabletting and forming after secondary ball milling, and sintering at 1600 ℃ to obtain the uniform and compact lanthanum zirconate ceramic material with low thermal conductivity and high bending strength. The invention is based on a lanthanum zirconate material with lower thermal conductivity, adopts Y and Ce to substitute and synthesize a precursor with a specific chemical composition ratio, and is added with BaTiO 3 The post-high-temperature sintering is carried out, the process is simple, the obtained ceramic material has high sintering density, and the bending strength is improved by 65-227%; the thermal conductivity is 1.20 to 1.50 W.m ‑1 ·K ‑1 Meanwhile, the heat insulation protective device can play a role in heat insulation protection in devices such as a traveling wave tube collector and a gas turbine, and meanwhile, the service life of the devices is prolonged. |
