Abstract
This research aimed to study the effect of sintering time variations in obtaining cobalt oxide nanoparticles [CoO and or Co3O4]. This research used cobalt(II) nitrate hexahydrate [Co(NO3)2·6H2O] as the precursor and ethylene glycol [C2H6O2] as the dissolvent. Then used the sintering process at 700˚ C with sintering times of 1, 2, and 3 hours. Next, characterizing the cobalt oxide used X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and Fourier Transform Infrared (FTI) tests. Data analysis showed that the process generated single-phase Co3O4 where the 2 hours sintering process produced the smallest crystallite diameter.
