Dynamic optical properties of metal hydrides
WebAug 31, 2024 · One interesting and unique characteristic of these hydrides are that they can be nonstoichiometric, meaning basically that the fraction of H atoms to the metals are not fixed. Nonstoichiometric compounds have a variable composition. WebAug 13, 2024 · Many metallic hydrides show metallic conductivity. LaNi 5 is an intermetallic compound of lanthanum and nickel. It occludes nearly 6 hydrogen atoms per unit lattice and is converted to LaNi 5 H 6. It is one of the candidates for use as a hydrogen storage material with the development of hydrogen-fueled cars.
