Scandium hydride (ScH3) NEW

Chemical Name: Scandium Hydride
Chemical Formula: ScH₃
Molecular Weight: 47.96 g/mol

Description:
Scandium hydride (ScH₃) is an inorganic compound composed of scandium and hydrogen. It is a member of the rare earth metal hydrides family and is known for its ability to absorb and store hydrogen. Scandium 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:

1. Hydrogen Storage: ScH₃ 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.

2. Catalysis: It may serve as a catalyst or catalyst precursor in hydrogenation or dehydrogenation reactions.

3. Research: Scandium hydride is used in materials science research to explore its properties and potential applications in advanced technologies.

Properties:

• Appearance: Gray or black solid

• Density: ~2.6 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 (ScH₃).

Safety Information:
Scandium 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.
