Abstract

The effect of bismuth oxide properties for varistor applications have been
investigated. The Bi203 doped ZnO with composition [(100X)%
ZnO)+(X%Bi2O3)]mol% have been prepared using solid state method. The
structural and morphological properties of synthesized Bi2O3-doped ZnO structures
have examined. Four different composition of Bi2O3 and ZnO have been applied to
the samples. All the samples were characterized using Scanning Electron
Microscope (SEM), X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR)
and UV-visible spectroscopy. The increasing of Bi2O3 concentration has led to
decrease in the average grain size and crystallite size. Therefore, by varying the
concentration of the dopant will influence the structural and morphological
properties of Bi2O3 doped ZnO varistor and will increase the performance of
varistor application. The Bi2O3 doped ZnO based varistor that have been sintered
at 1050°C with 1.0mol% of Bi2O3 has obtained the smallest grain size and exhibited
the most excellent varistor characteristics
