A method of treating a carbon structure is provided. The method may include the step of infiltrating the carbon structure with a ceramic preparation comprising yttrium oxides and zirconium oxides. The carbon structure may be densified by chemical vapor infiltration (CVI) and heat treated to form yttrium oxycarbides and/or carbides and zirconium oxycarbides and/or carbides. Heat treating the carbon structure may comprise a temperature ranging from 1000° C. to 1600° C.

1. A method of treating a carbon structure, comprising: infiltrating the carbon structure with a ceramic preparation comprising yttria-stabilized zirconia;densifying the carbon structure by chemical vapor infiltration (CVI); andheat treating the carbon structure to form a plurality of ceramic particles in the carbon structure comprising at least one of zirconium oxycarbide, zirconium carbide, yttrium oxycarbide or yttrium carbide. 2. The method of claim 1, wherein the ceramic preparation comprises at least one of a colloidal suspension or a sol gel. 3. The method of claim 1, further comprising partially densifying the carbon structure before the infiltrating the carbon structure with the ceramic preparation. 4. The method of claim 1, further comprising partially densifying the carbon structure after the infiltrating the carbon structure with the ceramic preparation, forming a partially densified carbon structure. 5. The method of claim 4, further comprising infiltrating the partially densified carbon structure with the ceramic preparation. 6. The method of claim 1, further comprising adding a polyelectrolyte dispersant to the ceramic preparation to coat the yttria-stabilized zirconia with a carbon film. 7. The method of claim 1, further comprising adding a carbon source to the ceramic preparation, the carbon source comprising carbon black. 8. The method of claim 1, further comprising adding a carbon source to the ceramic preparation, wherein the carbon source comprises at least one of polyvinyl alcohol, polyacrylamide, polyvinylpyrrolidone, polyvinyl acetate, polyethyleneimine, polyacrylate, or an aqueous emulsion of polyester, epoxy, or phenolic. 9. The method of claim 1, wherein, after the heat treating, the plurality of ceramic particles comprise, by weight, 0.5% to 12% of the carbon structure. 10. The method of claim 1, wherein each ceramic particle of the plurality of ceramic particles comprises a size of less than 500 nanometers. 11. The method of claim 1, wherein the heat treating the carbon structure comprises a temperature ranging from 1000° C. to 1600° C. 12. The method of claim 1, wherein the yttria-stabilized zirconia comprises about 5.2% by weight yttria or at least one of about 7, about 10.3, about 13.3 or about 15.9% by weight yttria. 13. A method of treating a carbon structure, comprising: forming the carbon structure;treating the carbon structure with heat at a first temperature ranging from 1000° C. to 2200° C.;infiltrating the carbon structure with a ceramic preparation comprising at least one of a ceramic colloidal suspension or a sol gel, the ceramic preparation comprising yttria-stabilized zironia;densifying the carbon structure by chemical vapor infiltration (CVI); andtreating the carbon structure with heat at a second temperature ranging from 1000° C. to 1600° C. to form a plurality of ceramic particles in the carbon structure comprising at least one of zirconium oxycarbide, zirconium carbide,yttrium oxycarbide or yttrium carbide. 14. The method of claim 13, further comprising partially densifying the carbon structure before the infiltrating the carbon structure with the ceramic preparation. 15. The method of claim 13, further comprising partially densifying the carbon structure after the infiltrating the carbon structure with the ceramic preparation, forming a partially densified carbon structure. 16. The method of claim 15, further comprising infiltrating the partially densified carbon structure with the ceramic preparation. 17. The method of claim 13, wherein, after the heat treating, the plurality of ceramic particles comprise, by weight, 0.5% to 12% of the carbon structure. 18. The method of claim 13, wherein the yttria-stabilized zirconia comprises about 5.2% by weight yttria or at least one of about 7, about 10.3, about 13.3 or about 15.9% by weight yttria. 19. The method of claim 13, further comprising adding a polyelectrolyte dispersant to the ceramic preparation to coat the yttria-stabilized zirconia with a carbon film.
