Carbon black samples from twelve runs on the 10S furnace have been evaluated in A size organic depolarizer primary cells. Service life to 0.9V at continuous load of 16-23 ohms ranged from about 19 to 25 hours. Oil feed rate and oxygen enrichment at two positions in the furnace were all significant. The presence of a vanadium additive in the feed oil increased service life about one hour. Data are presented on physical and chemical characteristics of the blacks. High service life was significantly associated with high values of color, tinting strength, and iodine surface area. Author
