Investigation of Structural and Optical Properties of ZrO2 Nanoparticles by Radiation-thermal and Thermal Methods
The X-ray diffraction spectrum of the nano-ZrO2 compound was drawn by the Ritveld method and the crystal structure was determined at room temperature and under normal conditions. The surface images of nano-ZrO2 and the corresponding energy spectra were captured at room temperature by the SEM method. This study the corresponding energy spectra of nano-ZrO2 and […]

Description
The X-ray diffraction spectrum of the nano-ZrO2 compound was drawn by the Ritveld method and the crystal structure was determined at room temperature and under normal conditions. The surface images of nano-ZrO2 and the corresponding energy spectra were captured at room temperature by the SEM method. This study the corresponding energy spectra of nano-ZrO2 and examines the elemental composition of the sample taken. In this process, water molecules are absorbed on the surface of nano-ZrO2. Radiation-thermal decomposition of water on nanosized ZrO2 in the temperature range of 300÷673 K has been studied by FTIR and Raman spectroscopy. It has been shown that nanosized zirconium dioxide adsorbs water on via the molecular and dissociative mechanisms. Intermediate products of the radiation-induced heterogeneous decomposition of water, namely, the molecular oxygen and hydrogen peroxide radical ions, zirconium hydride, and hydroxyl radicals have been detected.
