Zirconium oxide has found extensive applications in various industries because
of its excellent properties such as high strength; high-temperature resistance;
extraordinary wearing resistance; ionic conductivity; and corrosion resistance. Also, some
Properties like high melting point, high mechanical and thermal strength, high dielectric
constant and low conductivity have introduced this material as a prominent candidate for
engineering applications. In this study, zirconium oxide (ZrO2) Nano fibers was
synthesized by calcination of propoxide zirconium oxide/polyvinyl alcohol using sol-gel
and electrospinning methods. The morphology of the Nano fibers was verified by
scanning electron microscopy (SEM) and its crystalline phase was investigated by x-ray
diffraction and energy-dispersive x-ray spectroscopy (EDS). The mean diameter of the
Nano fibers varied in the range of 70-200 nm. XRD patterns also indicated the presence
of monoclinic and tetragonal phases in the Nano fibers calcined at 700 ℃. Results also
revealed that this new precursor can be used in the electrospinning technique to obtain
ZrO2 Nano fibers with relatively high purity. پرونده مقاله
