The results show that the zirconium sol has good spinnability when n: n= 1:3, reaction time is 6h and aging temperature is 15℃. The ZrO_2precursor fibers are made from hydrous zirconia chelated by acetylacetone. The sintercd fibers arecomposed of metastable tetragonal phase and sized about 15μm in diameter. Moreover, there aremany pores inside the fibers, but no cracks.4. ZrO_2/PVP hybrid fibers were prepared by blending the spinnable zirconium sol and 10 wt%PVP solution.
