The objective of this proposal is the Synthesis of a 25-gm sample of Alpha Polymorph, Rhombic Cube of Aluminum Trihydride, AlH3, "Alane," and provide characterization, analysis, and delivery to government laboratories for evaluation. The result will demonstrate the feasibility of producing Polymorphic Aluminum Hydride in a single-phase reaction between vaporous aluminum and hydrogen. This Phase I proposal including option, will demonstrate the objective stated above as verification-of-process for a Phase II apparatus, the Mobius Trans-Metals Inc., Advanced Metal Gas Vapor Reactor, AMGVR, in order to scale-up the process to pound quantities for larger-scale evaluation and process research as well as establish parameters to define mini-pilot plant design of pure Alpha Alane (2000 pounds/year scale)
