The invention relates to micronano zirconia fibers and a preparation method thereof. Use basic zirconium carbonate and glacial acetic acid to react, add yttrium salt crystal phase stabilizer, spinning aid and solvent, filter to remove insoluble impurities, and directly obtain zirconia precursor spinning sol with excellent spinnability in one step, and use centrifugal spinning Silk or electrospinning, combined with heat treatment technology to obtain zirconia fibers with diameters of 1-4μm and 100nm-1μm respectively, can be used in the range of -269-2300°C. The method directly prepares continuous spinnable spinning sol by one-step method, adopts two methods of centrifugal spinning and electrospinning to obtain micronano zirconia fibers, is simple to operate, easy to realize, reduces preparation cost, and is more beneficial to the environment Protect. |
