چکیده
Zirconium oxide has found extensive applications in various industries becauseof its excellent properties such as high strength; high-temperature resistance;extraordinary wearing resistance; ionic conductivity; and corrosion resistance. Also, someProperties like high melting point, high mechanical and thermal strength, high dielectricconstant and low conductivity have introduced this material as a prominent candidate forengineering applications. In this study, zirconium oxide (ZrO2) Nano fibers wassynthesized by calcination of propoxide zirconium oxide/polyvinyl alcohol using sol-geland electrospinning methods. The morphology of the Nano fibers was verified byscanning electron microscopy (SEM) and its crystalline phase was investigated by x-raydiffraction and energy-dispersive x-ray spectroscopy (EDS). The mean diameter of theNano fibers varied in the range of 70-200 nm. XRD patterns also indicated the presenceof monoclinic and tetragonal phases in the Nano fibers calcined at 700 ℃. Results alsorevealed that this new precursor can be used in the electrospinning technique to obtainZrO2 Nano fibers with relatively high purity.
