Abstract
The disclosure provides for methods of oxidizing carbide anions, or negative ions, from salt like carbides at low temperatures below about 600° C. In another aspect, the disclosure provides for reactions with intermediate transition metal carbides. In yet another aspect, the disclosure provides for a system of reactions where salt-like carbide anions and intermediate carbide anions are oxidized to produce pure carbon of various allotropes.
Claims20
A method of oxidizing carbide anions and/or negative ions from carbides, said method comprising:
- oxidizing carbide anions at a reaction temperature of below 600° C., wherein the reaction produces an allotrope of carbon in an sp1 and/or sp3 configuration.
A method of producing pure elemental allotropes of carbon comprising:
- oxidizing salt-like carbide anions and/or intermediate carbide anions at a reaction temperature of below 600° C.
A method for producing diamonds by reacting carbides with molten metallic halide salts at temperatures below 600° C.
A method of controlling a carbon allotrope comprising:
- controlling the reduction potential of a low melting point halide salt reactant by varying the reduction potential of a cation and/or changing the temperature of the melt.
