Furnace blacks, structural parameters

Table 4. Structural parameters for various furnace blacks 43)...

Eq. (32) contains no parameters characteristic of the filler. If it successfully represents data on one carbon black, then it should also do so for other blacks, irrespective of particle size or structure. The author s fragmentary data (212) on large particle furnace blacks indicates that this is true. The effects of carbon black structure at constant particle size are shown in Fig. 23 with data on the four carbons of Fig. 11. Although there is some scatter in the experimental points there is no systematic deviation by black structure. The line drawn through the data agrees nearly quantitatively with that of Harwood and Payne.
