Description

General description

Sodium hydride can be easily formed by reacting sodium metal with hydrogen gas at elevated temperatures. NaH is highly sensitive to moisture and air. It may be used as a strong reducing agent in the deintercalation of topotactic oxide. The crystal structure constitutes of a cubic Na with interstitial hydride ions. Sodium hydride exhibits a high gravimetric hydrogen storage capacity.
