Description
Summary:In this study, the experimental characterization of cerium oxide (CeO 2 ) powders doped with Ag at various amounts of 1, 2, 3, and 4 at.% was done using X-ray diffraction (XRD), differential thermal analysis (DTA), thermogravimetric analysis (TGA), Fourier transform infrared (FTIR) spectroscopy, Raman analysis, scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and vibrating sample magnetometry (VSM). The formation of the single phase of CeO 2 , having the cubic crystal structure, for all samples was observed. The phase structure was not affected by the as-used Ag contents. The addition of Ag caused an increase in the lattice parameter and a decrease in the crystallinity. In addition to these, non-gradual changes in the crystallite size were observed. The thermal stability for each sample was seen for each sample until 1000 °C. The morphology composed of the microparticles was observed. The magnetization and magnetic susceptibility values were affected by the amount of Ag dopant.
