中文摘要	lanthanide hexaaluminates including lamgal11o19, ndmgal11o19, smmgal11o19 and gdmgal11o19 were synthesized via sol-gel method. due to the anisotropic crystal growth, these oxides crystallize in the form of platelets and the platelet thickness increases with the decrease of rare-earth ionic radius. it was observed that the thermal-shock resistances of lamgal11o19, ndmgal11o19 and smmgal11o19 oxides were superior to 8ysz as proved by water quenching tests. in addition, the thinner the platelet. the more interstices are retained in the sintered specimen, and the better thermal-shock resistance the oxide has. based on sem images, it can be seen that the smmgal11o19 sample exhibits a mixture of the intergranular and transgranular fracture after thermal cycling failure.
