Abstract

Anisotropie pitch B issued from a coal tar pitch A is a mixture of isotropic phase 1 containing Brooks and Taylor mesophase spheres and an edge-to-edge type of gel 2.3. The latter is a two-phasedisperse system made of an anisotropic network 2 of carbon basic structural units (BSU), associated edge-to-edge, including isotropic microdroplets 3. The gel is quinoline soluble-toluene insoluble (QS.TI) (i.e., β resins and able to swell in tar).
