Chemical Name: Yttrium Hydride
Chemical Formula: YH₃
Molecular Weight: 91.91 g/mol
Description:
Yttrium
hydride (YH₃) is an inorganic compound composed of yttrium and
hydrogen. It is a member of the rare earth metal hydrides family and is
known for its ability to absorb and store hydrogen. Yttrium hydride
typically appears as a gray or black solid and is of interest in
materials science and energy storage due to its hydrogen storage
capabilities.
Uses:
Hydrogen Storage:
YH₃ is studied for its potential in hydrogen storage systems, as it can
reversibly absorb and release hydrogen gas, making it useful for clean
energy applications.
Catalysis: It may serve as a catalyst or catalyst precursor in hydrogenation or dehydrogenation reactions.
Research:
Yttrium hydride is used in materials science research to explore its
properties and potential applications in advanced technologies.
Properties:
Appearance: Gray or black solid
Density: ~4.24 g/cm³ (approximate)
Stability: Stable under normal conditions but reacts with water or acids to release hydrogen gas.
Hydrogen Content: High hydrogen storage capacity due to its trihydride form (YH₃).
Safety Information:
Yttrium
hydride is reactive with water and acids, releasing flammable hydrogen
gas. It should be handled in an inert atmosphere (e.g., argon or
nitrogen) to prevent unintended reactions. Proper personal protective
equipment (PPE), including gloves, goggles, and a lab coat, should be
worn. Avoid exposure to moisture and store in a dry, sealed container.
