Synthesizing and Characterization of Monoclinic and Tetragonal Phases of Zirconium Oxide (Zro2) Nanofibers with the Aid of Electrospinning Technique

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.
