Desorption of Hydrogen from CeNi₃ Intermetallic Hydrides

After hydrogen desorption from hydrides based on crystal and partly amorphous CeNi3 compounds samples were obtained with a composition CeNi3Нx (x = 0.5, 0.9). All samples were investigated by X-ray diffraction under the usual conditions. It was revealed that samples after hydrogen desorption have hexagonal and orthorhombic structure of the metallic matrix with cell parameters close to the initial alloy CeNi3. Such structural behavior under hydrogen desorption is determined by the desorption conditions and depends on different hydrogen diffusion in the lattice.
