Application

Sodium hydride (dry) (NaH) can be used for a variety of applications such as:

• preparation of sodium aluminum hydride (NaAlH₄), which can be used as a hydrogen storage material
• a base and a reducing agent for the deprotonation of alcohols, phenols, amides, ketones, and different functional groups
• a hydride donor that can be used in various reactions such as nitriles, amides, and imines
• for potential usage in thermal energy storage

Direct intercalation into C₆₀ results in the superconducting material (NaH)₄C₆₀.
