Zirconia fiber is widely used in the field of fire resistance and heat insulation because of its excellent thermal insulation performance. In this study, the hollow plant fiber, akund, was used as template to prepare zirconia fibers with hollow structure. SEM, XRD, mercury porosimetry, and TG-DSC were used to characterize the microstructure, phase and crystal structure, pore size distribution, and formation process of the zirconia fiber. The analysis shows that the hollow structure restricted the air flow and was conducive to the improvement of thermal insulation performance. Yttria doping mae the phase of zirconia fiber stable. Lower heat treatment temperature made the grain size smaller. The concentration of impregnating solution can influence on the fiber morphology.
