Title: Formation of high quality alane

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.

Methods for synthesizing alane without the formation of adducts and free of halides

Patent Zidan, Ragaiy; Knight, Douglas A; Dinh, Long V

A process is provided to synthesize an alane without the formation of alane adducts as a precursor. The resulting product is a crystallized .alpha.-alane and is a highly stable product and is free of halides.

Mechanochemical solid/liquid reaction in formation of alane

Patent Zidan, Ragaiy; Ward, Patrick A.

Methods for forming alane are described. The method drives the alane producing chemical reaction by a mechanical energy source such as a ball mill and includes stabilization of the product with solvent. At least one of the reactants is insoluble in the solvent. Thus, the product is both stabilized and phase-separated from the reactant(s) immediately upon formation. The method can be used to form .alpha.-alane, for instance for use in hydrogen storage.

A thin silicon solar cell having a back dielectric passivation and rear contact with local back surface field is described. Specifically, the solar cell may be fabricated from a crystalline silicon wafer having a thickness from 50 to 500 micrometers. A barrier layer and a dielectric layer are applied at least to the back surface of the silicon wafer to protect the silicon wafer from deformation when the rear contact is formed. At least one opening is made to the dielectric layer. An aluminum contact that provides a back surface field is formed in the opening and on the dielectricmore » « less

Enhancing electrochemical methods for producing and regenerating alane by using electrochemical catalytic additive

Patent Zidan, Ragaiy

A process of using an electrochemical cell to generate aluminum hydride (AlH.sub.3) and other high capacity hydrides is provided. The electrolytic cell uses an electro-catalytic-additive within a polar non-salt containing solvent to solubilize an ionic hydride such as NaAlH.sub.4 or LiAlH.sub.4. The resulting electrochemical process results in the formation of AlH.sub.3 adduct. AlH.sub.3 is obtained from the adduct by heating under vacuum. The AlH.sub.3 can be recovered and used as a source of hydrogen for the automotive industry. The resulting spent aluminum can be regenerated into NaAlH.sub.4 or LiAlH.sub.4 as part of a closed loop process of AlH.sub.3 generation.

Two step novel hydrogen system using additives to enhance hydrogen release from the hydrolysis of alane and activated aluminum

Patent Zidan, Ragaiy; Teprovich, Joseph A.; Motyka, Theodore

A system for the generation of hydrogen for use in portable power systems is set forth utilizing a two-step process that involves the thermal decomposition of AlH.sub.3 (10 wt % H.sub.2) followed by the hydrolysis of the activated aluminum (Al*) byproduct to release additional H.sub.2. Additionally, a process in which water is added directly without prior history to the AlH.sub.3:PA composite is also disclosed.
