152. Study of the microstructure of carbon blacks. J. B. Donnet and J. Schultz (&ole Su@ieure de Chimie, Mulhouse, France). The oxidation of a thermal black either by silver bichromate in sulphuric medium or by a solution of nitric acid leads to some samples ofoxidized carbon blacks which permit separate study of the inside and the outside of the particle. The study by electron microscopy, by X-ray diffraction, and by thermal treatment pointed out that the external layer of the particle is made of well organized crystallites, parallel to the surface, and contains an important closed porosity; the central part has a lower degree of organization.
