Abstract
A method for the manufacture of a carbon composite comprises compressing a combination comprising carbon and a binder at a temperature of about 350° C. to about 1200° C. and a pressure of about 500 psi to about 30,000 psi to form the carbon composite; wherein the binder comprises a nonmetal, metal, alloy of the metal, or a combination thereof wherein the nonmetal is selected from the group consisting of SiO2, Si, B, B2O3, and a combination thereof; and the metal is selected from the group consisting of aluminum, copper, titanium, nickel, tungsten, chromium, iron, manganese, zirconium, hafnium, vanadium, niobium, molybdenum, tin, bismuth, antimony, lead, cadmium, selenium, and a combination thereof.
