ABSTRACT

The substitution of Mg with Cu to produce Mg_0.98Cu_0.02O and Mg_0.96Cu_0.04O are done to investigate the effect of Cu substitution on the characteristics of the modified MgO. The samples are synthesized using a combustion method. The samples obtained are annealed at 900 ºC for 24 hours. The phase and purity of samples are studied using X-Ray diffraction (XRD) and it revealed that the samples are pure and of cubic crystal structure. The morphology and crystallites size of the samples are examined by a field emission scanning electron microscope (FESEM), the JEOL JSM-7600F. Results showed that the crystallite size of samples increases after Cu substitution.
