Claim Text:
1. A method for producing a carbonized filler, said method comprising the following steps: putting a filler in the reaction zone of a reactor, heating and setting the temperature ranging from 400 to 500° C. under the protective atmosphere, adding hydrogen at first stage; at second stage, heating and setting the temperature ranging from 600 to 1200° C. and simultaneously adding a mixture of hydrogen and carbon source gas, then maintaining the final temperature for 0.1 to 5 hours; then adding nitrogen and removing heating source, cooling, and the carbonized filler being resulted; wherein maintaining said filler in fluidized state by adding the gas through the lower part of the reaction zone of the reactor during reaction process; wherein said filler is one or more of materials selected from a group consisting of mineral material, metal oxide, antimony sulfide, silicon carbide, silicon nitride, silicon dioxide, carbonates, titanate, silicate and metallic elementary substance.
