CARBON-COATED POROUS SILICA POWDER, PROCESS FOR PRODUCING THE SAME, AND CONDUCTIVE RESIN COMPOSITION CONTAINING THE POWDER

摘要

A process for producing a carbon-coated porous silica powder which comprises the step of heating organic-compound particles coated with a silica component in a non-oxidizing atmosphere to thereby carbonize the organic-compound particles and shape the silica component into the form of hollow spheres or the like and, simultaneously therewith, deposit the carbon generated by the carbonization to the surface of the silica component; a porous silica powder the surface of which has been coated with carbon and which is produced by the process; and a conductive resin composition which comprises a resin and the silica incorporated therein.
