Summary: | The Si doped ZnO nanopowders for varistor have been prepared at
different sintering temperature using solid state method. The Si doped
ZnO have been sintered at different temperatures 850, 950 and 1050 °C
at air condition. The structural and densification of Si doped ZnO were
determined using scanning electron microscopy (SEM), X-ray diffraction
(XRD) analysis and digital density meter. It was found that the average
grain size of Si doped ZnO varistor were 0.81, 1.05 and 2.10µm when
sintered at 850, 950 and 1050 °C, respectively. The density of Si doped
ZnO were 3.999, 4.453 and 5.332 g/cm when the sintering temperature
increased from 850, 950 and 1050 °C, respectively. The density and
average grain size of the Si-Doped ZnO is increased with increase of
sintering temperature. The Si doped ZnO varistor at different sintering
process are polycrystalline structure. It is revealed that the sintering
temperature can influence the properties of Si doped ZnO ceramics
which is suitable to be used in varistor application. |
