| 摘 要： | 本研究提出了一种利用离心纺丝技术制备稳定碳化锆(ZrC)纤维的有效方法。此方法使用醋酸锆和蔗糖作为锆源和碳源, 聚乙烯吡咯烷酮(PVP)作为纺丝助剂, 经过1600 ℃的裂解与碳热还原热处理后, 所纺原丝转化成由均匀纳米ZrC晶体组成的ZrC纤维。研究结果表明, 纤维中残留的少量碳可助力ZrC纤维在2000 ℃的超高温环境下仍保持较好的结构稳定性。 |

| Abstract: | In this work, an efficient approach was presented to produce stable zirconium carbide (ZrC) fibers by centrifugal spinning technique. Zirconium acetate and sucrose were used as the zirconium source and carbon source respectively. And polyvinyl pyrrolidone (PVP) was used as the spinning aid. After pyrolysis and carbothermal reduction at 1600 ℃, the as-spun green fibers can be converted to homogeneous ZrC fibers composed of uniform nano-sized ZrC crystals. Moreover, it is revealed that the as-fabricated ZrC fibers can sustain superior microstructure stability at an ultra-high temperature up to 2000 ℃, benefiting from a limited amount of residual carbon. The reaction mechanisms and the resulted ZrC fibers were also investigated. |
| Keywords: | zirconium carbide fiber centrifugal spinning ultra-high temperature stability |
