The invention relates to carbon black having a C-14 content greater than 0.05 Bq/g and a ratio ΔD50/Dmode of the aggregate size distribution of less than 0.7. The carbon black is produced by thermal oxidative pyrolysis or thermal cleavage of the carbon black raw material in that the carbon black raw material contains renewable carbon black raw materials and an oxygen deficiency is present in the pyrolysis/cleavage reaction. The carbon blacks can be used in rubber and rubber mixtures, plastic, printing inks, inks, inkjet inks, toners, lacquers, paints, paper, adhesives, batteries, pastes, bitumens, concrete, and other building materials and as reducing agents in metallurgy.
Carbon black, wherein the C-14 content is greater than 0.05 Bq/g and the ΔD50/Dmode ratio of the aggregate size distribution is smaller than 0.7.
