Method for preparing yttrium aluminum oxide ceramic precursor
The invention discloses a method for preparing an yttrium aluminum oxide ceramic precursor. An aluminum source and a yttrium source are dissolved in an organic solvent according to a certain proportion, a complexing agent is adopted for conducting coordination stabilization on the mixed solution, then hydrolytic polycondensation is conducted, the spinning performance of a precursor is improved by adjusting a synthesis process according to different yttrium-aluminum element proportions, and then the yttrium-aluminum oxide continuous ceramic fiber composed of different crystal phases is prepared. The high-temperature grain size stability and the high-temperature resistance of the fiber are improved. The softening point of the yttrium aluminum oxide ceramic precursor is 110-180 DEG C, and the highest ceramic yield is 39%.
本发明公开了一种制备钇铝氧化物陶瓷前驱体的方法。按照一定比例将铝源与钇源溶解在有机溶剂中，采用络合剂对混合溶液进行配位稳定后进行水解缩聚，针对不同钇铝元素比例，通过调整合成工艺，提高了前驱体的纺丝性能，进而制备得到不同晶相组成的钇铝氧化物连续陶瓷纤维，提高了纤维的高温晶粒尺寸稳定性及耐高温性能。所述钇铝氧化物陶瓷前驱体软化点介于110‑180℃，陶瓷产率最高39％。
