CARBON BLACK AND PRODUCTION METHOD THEREFOR, AND ELECTRICITY STORAGE DEVICE AND CONDUCTIVE RESIN COMPOSITION

摘要

In carbon black of the present invention, peak intensity I A of a main peak derived from Fe 3 C, peak intensity I B of a main peak derived from FeS, and peak intensity I C of a main peak derived from FeO(OH) in a radial distribution function, which is obtained by performing Fourier transform with respect to a broadband X-ray absorption fine structure spectrum of a K absorption edge, satisfy 0.7 ‰¤ I A / (I B + I C ) ‰¤ 6.0. A production method for a carbon black of the present invention includes subjecting raw material carbon black to a heat treatment at a temperature of 900°C to 1500°C for a time of 5 minutes to 180 minutes under an atmosphere of a halogen element-containing gas.
