    Abstract: In an embodiment, a method includes producing a mixed feedstock of at least three halogenated monomer feedstocks. A first of the at least three halogenated monomer feedstocks includes an SP3 carbon, a second of the at least three halogenated monomer feedstocks includes an SP2 carbon, and a third of the at least three halogenated monomer feedstocks includes at least two SP1 carbons. The method further includes producing a polyorbital-hybrid pre-ceramic polymer comprising the SP1 carbons, the SP2 carbon, and the SP3 carbon. The polyorbital-hybrid pre-ceramic polymer is produced by reducing the mixed feedstock such that one or more halogen atoms are removed from the mixed feedstock. The method also includes fabricating the polyorbital-hybrid pre-ceramic polymer into a greenware form and producing a polyorbital-hybrid ceramic carbon comprising the SP1 carbons, the SP2 carbon, and the SP3 carbon. The polyorbital-hybrid ceramic carbon is produced by thermolyzing the polyorbital pre-ceramic polymer.
