Abstract
Method and compositions produced thereby concerning high specific surface area carbides and nitrides. The carbides and nitrides are obtained by thermal reduction of oxides in the presence of a source of carbon or nitrogen respectively, with relatively slow progressive temperature increases prior to completion of the reaction, followed by quenching.
