Ab s t r Ac t Magnesium oxide was hygroscopic solid mineral that occurs naturally as periclase. Magnesium oxide had high thermal conductivity, it gets heated when the electricity was passed through it. Magnesia crucible had a stability of 2400°C in air. 1700°C in reducing atmosphere. Magnesium oxide nanoparticles were obtained from the mixture of magnesium nitrate as precursor and sodium hydroxide as precipitating agent by sol-gel method. Finally, the resultant white crystalline powder of MgO was annealed at various temperatures of 80°C, 135°C and 180°C. The analytical studies ( XRD, SEM FTIR. EDAX) reveals the morphological characterization of MgO nanoparticles. The Scanning Electron Microscopy (SEM) indicates the structures of MgO nanoparticles. The crystal size of MgO nanoparticles was obtained by X-Ray Diffraction ( XRD). The optical properties of the sample were obtained by UVVisible spectroscopy. Fourier Transform infrared spectroscopy indicates powdered composition of the sample. EDAX indicates elementary composition of the MgO nanoparticles.
