Abstract
Methods for forming alane are described. The method includes addition of toluene at a temperature above the crystallization temperature of alane to a lower temperature solution that includes alane adduct, ether, and toluene. Upon the addition, a crystallization mixture is formed that is at or near the crystallization temperature of alane. The alane of the mixture crystallizes over a period of time to form a high purity alane polymorph.
