Abstract: 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.

Abstract: An electrically conductive resin composition characterized as containing a resin and electrically conductive platy particles having a carbon layer at the surface thereof and a true specific gravity of up to 3.0.

Abstract: A rubber composition is obtained which exhibit improved strength, abrasion resistance and antistatic properties, as well as low rolling resistance. The rubber composition is characterized as being rendered conductive by incorporating into rubber a silica filler having a conductive surface layer as composed of carbon or conductive tin oxide.
