Abstract
Zirconia (ZrO2), an inorganic material, is a very fascinating material due to its high mechanical strength and fracture toughness. The synthesis is carried out by using co-precipitation method using optimum content of zirconium oxychloride octahydrate (ZrOCl2.8H2O) with NaOH solution at calcination temperature of 700°C. The synthesized samples were characterized to ensure structural, functional, morphological and chemical composition by several techniques. The monoclinic structure has been confirmed from XRD, SAED and Raman spectra. The Zr-O stretching vibration and Zr-O2-Zr bending vibrations were confirmed through FTIR analysis. The well dispersed particles with spherical morphology were established through SEM and TEM analyses. EDX spectra confirmed the formation of pure zirconium oxide. The band gap was calculated with the help of UV-Vis spectra and particle size was determined form XRD data using Debye Scherrer’s equation. The variation of band gap and particle size compared with different concentrations of precursor solution was studied.
