Abstract

This research aims to study the effect of calcination temperature on ionic conductivity of CSZ pellets made through a sol gel method in three calcination temperatures of 500 oC, 600 oC and 700 oC. In this study, CSZ pellets were made from extraction of Zirconium Silicate (ZrSiO4) by caustic fusion and sol gel synthesis method. The characterization of CSZ pellets was performed using X-ray diffraction (XRD), Scanning Electron Microscope equipped with energy dispersive Xray spectroscopy (SEM-EDS), and LCR meter. XRD results verify that XRD pattern of CSZ pellets have similar pattern to that analysed for reference CSZ pellet which is a cubical structure. SEM images of CSZ pellets exhibited pores formation which influenced ionic conductivity value. The highest ionic conductivity value of CSZ pellets achieved at a calcination temperature of 700 oC with the measuring temperature of 600 oC is 4.83 x 10-5 S/cm. Therefore, the essential outcome of this research is the recommended optimum calcination temperature of CSZ pellets made through a sol gel method of 700°C.
