Abstract
Metal carbides can be formed by the pyrolysis of a composition comprising metal and carboxylic acid residues bonded therein, the composition being substantially free of extraneous carbon and also having metal moieties that are not in the substituent position. Dicarboxylic acids, for example, can be reacted with either metal alkoxides or metal halides to form an oligomer or polymer which can be calcined to the metal carbide. Alternatively, a metal alkoxide can be reacted with a monocarboxylic acid to form a metal alkoxide carboxylate which can be heated to the metal carbide. Finally, a metal carboxylate can be heated to form the desired metal carbide.
