Hafnium oxide continuous ceramic fiber and preparation method thereof
The invention discloses a hafnium oxide continuous ceramic fiber and a preparation method thereof. The method comprises the following steps: carrying out melt spinning on a hafnium oxide polymer precursor block to obtain a fiber precursor; performing constant-temperature and constant-humidity treatment to obtain non-melting fibers; slowly heating and sintering to realize inorganic treatment to obtain inorganic fibers; and performing high-temperature heat-preservation sintering to realize ceramization treatment to obtain the hafnium oxide continuous ceramic fiber. The hafnium source is coordinated by using two complexing agents, the linear degree and molecular weight of the precursor are improved by adjusting the addition amount and variety of the two complexing agents, the hafnium oxide continuous ceramic fiber is prepared through a melt spinning method, and the obtained fiber is small in diameter and high in strength.
本发明公开了一种氧化铪连续陶瓷纤维及其制备方法。所述方法包括：将氧化铪聚合物前驱体块体进行熔融纺丝得到纤维原丝；恒温恒湿处理得到不熔化纤维；慢速升温烧结实现无机化处理得到无机化纤维；高温保温烧结实现陶瓷化处理，得到氧化铪连续陶瓷纤维。本发明通过使用两种络合剂对铪源进行配位，通过调节两种络合剂的添加量、种类，提高了前驱体的线性程度及分子量，通过熔融纺丝法制备氧化铪连续陶瓷纤维，所得纤维的直径细、强度高。
