✦ Synopsis

Abstr anthracene chars heat treated between 500 and 1200°C is developped and applied to d.c. electrical conductivity, paramagnetic susceptibility and apparent density. An inhomogeneous process for the carbonization is proposed, in agreement with recent results on the structure of these chars. acts 32. An examination of the origins and growth of mesophase in the liquid phase of carbonization

The pyrolysis of coal tar and petroleum pitches was studied under nitrogen pressures from 2 to 150 bar at temperatures between 300 and 600°C. The resulting residues were investigated by TGA, polarized-light microscopy and X-ray diffraction. It is shown that increasing pressure does not only increase

The carbonization of an industrial coal-tar pitch was studied by using a tube bomb, as a function of carbonization temperature (SSOY-SSOOC) and inert gas pressure (l-20 bar), and resultant green cokes were evaluated according to electrical resistivity determined using the Van der Pauw method. At 55O
