Yttrium/aluminum-organic polymer precursor, yttrium aluminum garnet continuous fiber and preparation method
The invention relates to an yttrium/aluminum-organic polymer precursor, an yttrium aluminum garnet continuous fiber and a preparation method; the preparation method comprises the following steps: synthesizing and preparing the yttrium/aluminum-organic polymer precursor, and preparing a precursor spinning sol from the yttrium/aluminum-organic polymer precursor; and preparing the precursor spinningsol into a precursor continuous gel fiber through dry spinning, and carrying out heat treatment on the precursor continuous gel fiber to obtain the yttrium aluminum garnet continuous fiber. Accordingto the method, the yttrium/aluminum-organic polymer is proposed as the precursor for the first time to prepare the yttrium aluminum garnet fiber, the oxide content in the yttrium/aluminum-organic polymer precursor is 35% or above, other components do not need to be added to serve as a spinning aid, and subsequent treatment of the spinning aid is avoided. The yttrium aluminum garnet continuous fiber prepared by the method is high in purity, high in strength, uniform and adjustable in diameter, good in flexibility, compact in structure and free of defects such as pores and cracks.
本发明涉及钇/铝‑有机聚合物前驱体、钇铝石榴石连续纤维及制备方法，该制备方法包括钇/铝‑有机聚合物前驱体的合成制备，并由其配制前驱体纺丝溶胶；再通过干法纺丝将前驱体纺丝溶胶制成前驱体连续凝胶纤维，前驱体连续凝胶纤维经过热处理，得到钇铝石榴石连续纤维。本发明首次提出钇/铝‑有机聚合物为前驱体制备钇铝石榴石纤维，钇/铝‑有机聚合物前驱体中氧化物含量大于35％，并且不需要加入其他成分作为纺丝助剂，避免了对后续纺丝助剂的处理。本发明制备的钇铝石榴石连续纤维纯度高、强度高、直径均匀且可调、柔韧性好、结构致密、无气孔、裂纹等缺陷。
