Abstract
The present invention relates to metals and matrix composites and methods of manufacture. A method of refining a metal oxide is shown. A method of forming a carbon nanotube metal matrix composite is shown using a metal oxide and an amount of carbon nanotubes. Processing is carried out using wave energy radiation such as microwave radiation. In some methods, processing is carried out while substantially isolated from external oxygen sources such as ambient air.
