Description

LITHIUM ALUMINUM HYDRIDE is a white powder that turns gray on standing. If spread out over a large flat combustible surface, friction can cause ignition. Used to make other chemicals, as a polymerization catalyst, as a hydrogen source, and as a propellant.

Lithium tetrahydroaluminate is a lithium salt.
