Abstract: Improved multi-layered amorphous metal-based oxygen anodes comprise a substrate material, a first coating of an amorphous metal alloy applied thereto and a second coating of a different amorphous metal alloy applied to the first coating. A method for the fabrication of such anodes comprises the step of applying a first coating of an amorphous metal alloy to a substrate material and applying a second coating of a different amorphous metal alloy to the first coating. An electrolytic process employing such anodes is also provided.

Abstract: Improved amorphous metal-based composite oxygen anodes comprise a substrate material, a first coating of an amorphous metal alloy applied thereto and a second coating of a mixed metal oxide applied to the first coating and fused therewith. A method for the fabrication of such anodes comprises the step of applying a first coating of an amorphous metal alloy to a substrate material, applying a second coating of a mixed metal oxide to the first coating and fusing the two layers together without crystallinity of the amorphous metal alloy. An electrolytic process employing such anodes is also provided.

Abstract: A thin film device for recording information in readable form that decreases its light absorbancy in response to increased temperature. The film includes two elements from column IVa of the Periodic Table, such as silicon, germanium, tin and lead, bound with one of or a mixture of sulfur and selenium.The as-deposited inventive materials contain tetrahedral units, some ethane-like units and some rings and chains. Upon heating the ethane-like units are converted to rings and chains and tetrahedral units producing a dramatically decreased light absorbancy. The materials are stable at relatively high operating temperatures.

Abstract: Amorphous metal alloy compositions are synthesized by solid state incorporation/reduction reactions wherein a high-surface area support is brought in contact with a precursor metal-bearing compound in such a manner that the compound is incorporated into the support or caused to deposit metal onto the surface of the support. The composition obtained is an amorphous alloy composition or can be made so by heat treating at a temperature below the crystallization temperature of the amorphous metal alloy desired to be formed.

Abstract: Amorphous metal alloy shapes are synthesized by providing an intimate mixture of the components of the amorphous alloy, which mixture includes at least one ductile component. The mixture may be subjected to well-known forming techniques at a temperature below the crystallization temperature of the amorphous metal alloy to be formed. The ductile component of the mixture acts as a binder matrix to provide strength and uniform properties to the formed object.
