Aluminum-carbon compositions

摘要

An aluminum-carbon composition including aluminum and carbon, wherein the aluminum and the carbon form a single phase material, characterized in that the carbon does not phase separate from the aluminum when the single phase material is heated to a melting temperature.

1. An aluminum-carbon composition comprising:
aluminum chemically bonded to carbon, wherein the aluminum and the carbon form a single phase material formed by mixing carbon into the aluminum while molten and applying electrical energy thereto, using an arc welder, to initiate an endothermic reaction between the aluminum and the carbon, characterized in that the single phase material is meltable and that the carbon does not phase separate from the aluminum when the single phase material is subsequently re-melted or is deposited as a film of the single phase material by magnetron sputtering or e-beam evaporation; wherein the single phase material is not aluminum carbide, Al4C3, nor an Al—C metal matrix composite, and has a nanoscale distribution of carbon interconnected by a network of carbon as viewed by a scanning electron microscopy image at one micrometer.
