  • CARBON BLACK AND PRODUCTION METHOD THEREFOR, AND ELECTRICITY STORAGE DEVICE AND CONDUCTIVE RESIN COMPOSITION
    Publication number: 20160190594
    Abstract: In carbon black of the present invention, peak intensity IA of a main peak derived from Fe3C, peak intensity IB of a main peak derived from FeS, and peak intensity IC 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?IA(IB+IC)?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.
