Al-Si copolymerized oxide ceramic precursor and preparation method thereof
The invention discloses an Al-Si copolymerized oxide ceramic precursor and a preparation method thereof. The softening point of the Al-Si copolymerized oxide ceramic precursor is between 80 DEG C and 190 DEG C; and the precursor is technically characterized in that in the Al-Si copolymerized oxide ceramic precursor, the compatibility of Al and Si components is high, atomic-scale uniform distribution can be realized, and the proportion is adjustable. The Al-Si complex-phase oxide continuous ceramic fiber prepared from the precursor has a high temperature resistance grade, the tensile strength is not less than 2.0 GPa, the tensile elastic modulus is not less than 200 GPa, and the strength retention rate after high-temperature heat treatment is not less than 70%.
本发明公开了一种Al‑Si共聚氧化物陶瓷前驱体及其制备方法。所述Al‑Si共聚氧化物陶瓷前驱体软化点介于80～190℃；本发明的技术关键在于Al‑Si共聚氧化物陶瓷前驱体中，Al、Si两组分相容性好，可实现原子级均匀分布，且比例可调。利用该前驱体所得Al‑Si复相氧化物连续陶瓷纤维具有较高的耐温等级，拉伸强度不小于2.0GPa，拉伸弹性模量不小于200GPa，高温热处理后的强度保留率不低于70％。
