✦ Synopsis

In pyrolytic graphite, PG, the X-ray scattering far from a Bragg reflection is all Compton modified radiation. A comparison of direct measurements shows that the Compton fraction in the scattering from disordered carbons, e.g. glassy carbon, can be calculated from measurements on PG and the adsorption coefficient of the disordered carbon.

246. Forms of particulate carbon in soot and carbon black

Avrom I. Medalia and Donald Rivin (Cabot Corporation, Concord Road, Billerica, MA 01821). At least four morphologically distinct forms of particulate carbon, one of which has not been recognized previously, can be identified in various types of soot. A form of carbon with clustured particulate morphology, which we propose to call "aciniform carbon", is the principal carbon component of diesel soot and carbon black. Due to their origin as a by-product, soots generally have considerably larger amounts of organic extract and/or ash than carbon black. 247.
