ABSTRACT:
A plurality of processes for producing unique end products containing elemental metals or metal oxides on and in a carbon substrate, elemental metals or metal oxides in the absence of such a carbon substrate, mixtures of elemental metals or metal oxides on and in a carbon substrate, or mixtures of elemental metals or metal oxides in the absence of such a carbon substrate, all of which processes involve the preparation of a first-step intermediate product that is a carbonaceous material appearing to be non-graphitic by X-ray diffraction standards and containing metal and halogen, which intermediate product is made from graphite fluoride and an appropriate metal halide. Among the end products are aluminum oxide fibers, elemental iron fibers, magnetic carbon fibers containing either iron or an iron-nickel alloy, and carbon containing various metals in the form of elemental metal or oxides.
