Chemical Name: Neodymium Hydride
Chemical Formula: NdH? (dihydride) or NdH? (trihydride)
Molecular Weight: 147.25 g/mol (NdH?), 165.26 g/mol (NdH?)

Description:
Neodymium hydride is an inorganic compound composed of neodymium and hydrogen. It typically exists in two forms: neodymium dihydride (NdH?) and neodymium trihydride (NdH?). These compounds are part of the rare earth metal hydrides family and are known for their ability to absorb and release hydrogen, making them useful in hydrogen storage applications. Neodymium hydride is a solid material, often appearing as a dark gray or black powder.

Uses:

1. Hydrogen Storage: Neodymium hydride is studied for its potential in hydrogen storage systems due to its ability to reversibly absorb and release hydrogen gas.

2. Catalysis: It can act as a catalyst or catalyst precursor in certain chemical reactions, particularly those involving hydrogenation or dehydrogenation processes.

3. Research: Neodymium hydride is used in materials science research to explore its properties and potential applications in energy and technology.

Properties:

• Appearance: blue powder

• Density: ~6.3 g/cm3 (NdH?, approximate)

• Stability: Stable under normal conditions but reacts with water or acids to release hydrogen gas.

• Hydrogen Content: High hydrogen storage capacity, especially in the trihydride form (NdH?).

Safety Information:
Neodymium 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.
