Preparation and Characterization of Yttrium Oxide Nanoparticles at Different Calcination Temperatures from Yttrium Hydroxide Prepared by Hydrothermal and Hydrothermal microwave Methods

The Synthesis of yttrium oxide nanoparticles have been achieved via calcination of yttrium hydroxide produced from the reaction of aqueous solutions of yttrium nitrate and sodium hydroxide at pH = 13 using hydrothermal and hydrothermal microwave methods. Effect of heat treatment of the resulted yttrium hydroxide powder on the morphology and crystallinity of the resulting oxide was studied at calcination 500, 700 and 1000°C to obtain. The resulted products were characterized by means of X-ray diffraction (XRD), scanning electron microscope (SEM), atomic force microscope (AFM), Fourier transform infrared spectrometer (FTIR) and thermal analyses (TG).
