Embodiment 1

[0155] As raw carbon black, 50 g (dry mass) of CB-1 powder was placed in the center of the furnace tube, while chlorine gas as a halogen-containing gas was flowed at 10 L / min, and argon gas was flowed at 1 L / min at the same time. Heat at 900°C for 30 minutes. Then, by starting the oil pressure diffusion pump, the vacuum degree is decompressed to 1.33×10 -1 ~1.33×10 -2 After maintaining Pa or below for 30 minutes, it cooled to 30 degreeC and obtained the evaluation sample.

Embodiment 2 and 3

[0157] Except having changed heating temperature as shown in Table 1, it carried out similarly to Example 1, and obtained the evaluation sample.

Embodiment 4～17

[0159] As shown in Table 1 and Table 2, except having changed the raw material carbon black used, heating temperature, and the gas containing a halogen element, it carried out similarly to Example 1, and obtained the evaluation sample.

Abstract

The present invention comprises carbon black, wherein the peak intensity (IA) of the main peak derived from Fe3C, the peak intensity (IB) of the main peak derived from FeS, and the peak intensity (IC) of the main peak derived from FeO(OH) satisfy 0.7 <= IA / (IB+IC) <= 6.0 in a radial distribution function obtained by performing Fourier transform on extended X-ray absorption fine structure spectra of the K absorption edge. This method for producing the carbon black involves heat treating a carbon black raw material at 900-1500 DEG C for 5-180 minutes under a halogen element-containing gas atmosphere.

Description

technical field [0001] The present invention relates to carbon black, a method for producing the same, an electrical storage device, and a conductive resin composition. [0002] This application claims the priority of Japanese Patent Application No. 2013-165223 for which it applied in Japan on August 8, 2013, and uses the content here. Background technique [0003] Carbon black is widely used in printing inks, conductivity-imparting agents for coatings and resins, rubber reinforcing materials, resin colorants, conductive additives for positive and negative electrodes of secondary batteries, and catalyst supports for fuel cells. [0004] Examples of methods for producing carbon black include (1) a furnace method in which raw materials are incompletely burned, and (2) a contact method in which raw materials are burned using a burner nozzle and the flame is brought into contact with channel steel to capture carbon black. , and (3) the heating method of thermally decomposing na...
