Yttrium aluminum oxide continuous ceramic fiber and preparation method thereof
The invention discloses an yttrium aluminum oxide continuous ceramic fiber and a preparation method thereof. The yttrium aluminum oxide continuous ceramic fiber is composed of Al2O3 and Y2O3, and the molar ratio of Al to Y is 5: (3.5-0.5); the crystal phase composition of the yttrium aluminum oxide continuous ceramic fiber is a mixture of a pure YAG (Y3A15O12) phase or a YAG phase and at least one of alpha-Al2O3, gamma-Al2O3 and YAM (Y4A12O9) phases. The average diameter of the yttrium aluminum oxide continuous ceramic fiber is 5-15 [mu] m, and the highest tensile strength can reach 1.5 GPa. Melt spinning fiber forming is adopted, the process is simple, environment friendliness is achieved, and large-scale production is facilitated.
本发明公开了一种钇铝氧化物连续陶瓷纤维及其制备方法。所述钇铝氧化物连续陶瓷纤维，由Al2O3、Y2O3组成，Al、Y元素的摩尔比为5:3.5‑0.5；所述钇铝氧化物连续陶瓷纤维的晶相组成为：纯YAG(Y3A15O12)相或YAG相与α‑Al2O3、γ‑Al2O3和YAM(Y4A12O9)相至少一种的混合。所述钇铝氧化物连续陶瓷纤维平均直径为5‑15μm，拉伸强度最高可达1.5GPa。本发明采用熔融纺丝成纤，工艺简单，环境友好，便于放大生产。
