Abstract
Methods of producing silicon carbide, and other metal carbide materials. The method comprises reacting a carbon material (e.g., fibers, or nanoparticles, such as powder, platelet, foam, nanofiber, nanorod, nanotube, whisker, graphene (e.g., graphite), fullerene, or hydrocarbon) and a metal or metal oxide source material (e.g., in gaseous form) in a reaction chamber at an elevated temperature ranging up to approximately 2400° C. or more, depending on the particular metal or metal oxide, and the desired metal carbide being produced. A partial pressure of oxygen in the reaction chamber is maintained at less than approximately 1.01×102 Pascal, and overall pressure is maintained at approximately 1 atm.

A method of producing silicon carbide material, comprising:
- reacting a carbon material and a silicon-containing gas in a reaction chamber at an elevated temperature of up to approximately 2400° C. and a pressure of about 1 atmosphere;
- and
- maintaining a partial pressure of oxygen in the reaction chamber of less than approximately 1.01×102 Pascal to produce the silicon carbide material.
