  • Patent number: 7897135
    Abstract: The present invention is generally directed to a novel, economic synthesis of oxide ceramic composites. Methods of the present invention, referred to as carbon combustion synthesis of oxides (CCSO), are a modification of self-propagating high-temperature synthesis (SHS) methods in which the heat needed for the synthesis is generated by combustion of carbon in oxygen rather than that of a pure metal. This enables a more economic production of the ceramic material and minimizes the presence of intermediate metal oxides in the product. The reactant mixture generally comprises at least one oxide precursor (e.g., a metal or non metal oxide, or super oxide, or nitride, or carbonate, or chloride, or oxalate, or halides) as a reactant, but no pure metal. Pure carbon in the form of graphite or soot is added to the reactant mixture to generate the desired heat (upon ignition). The mixture is placed in a reactor and exposed to gaseous oxygen.
