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.

Key words: zirconium carbide fiber, centrifugal spinning, ultra-high temperature stability
