  • Patent number: 6395245
    Abstract: A method for preparing a carbon-containing composition is disclosed which comprises the steps of introducing, into a hot gas, a dispersion obtained by dispersing, in a decomposable carbon compound, a metal oxide and/or a metal compound which can be converted into the metal oxide by heating, to form a carbon-containing composition containing simple carbon and the corresponding metal oxide; and then collecting the formed carbon-containing composition. This carbon-containing composition is useful for the manufacture of a ceramic powder for sintering.
