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 UV- Visible spectroscopy. Fourier Transform infrared spectroscopy indicates powdered composition of the sample. EDAX indicates elementary composition of the MgO nanoparticles.

Synthesis of strontium oxide nanoparticles was carried out by sol –gel method using strontium nitrate and sodium hydroxide at room temperature which is very simple and cost effective. The characterization of strontium oxide nanoparticles was done using X-ray diffraction, scanning electron microscopy (SEM) and Fourier transform infra-red (FTIR). X-ray diffraction pattern indicates that the nanoparticles are crystalline in nature. The crystalline size of strontium oxide nanoparticle was calculated by Debye-Scherrer formula. The crystalline sizes are about 80nm. The morphology of nanoparticles was observed and investigated using SEM. The material at room temperature, calcined at 2000C, 400 0C and 6000C respectively shows pseudo spherical shape, cubic form and finally it becomes cylindrical this shows that there is a agglomeration with increase in temperature. FTIR spectrum of strontium oxide shows the peak at 854.64 cm-1 which is due to Sr -O bond.
