Abstract
The invention discloses a method for preparing a carbon-silicon double-phase filler. In the method, an organic matter which contains silicon is sprayed into a combustion chamber in a carbon black furnace and is dissociated in a hot air flow to produce silicon ions; the dissociated silicon ions is mixed with sprayed raw material oil when entering a throat pipe section of a carbon black reaction furnace with the hot air flow; and the raw material oil is cracked, the carbon atoms produced by the cracking of the raw material oil gather around the silicon ions, the silicon ions serve as crystal nuclei and finally the filler with a carbon-silicon double-phase structure is formed.
