✦ Synopsis


The optical texture of the carbonaceous mesophase is related to the nature of the pitch precursor, the mesophase viscosity and mode of preparation. The anisotropic domain size, represented by the distance between extinction lines, has been a useful parameter for characterizing mesophase pitches. A procedure for quantitative determination of mesophase domain size, utilizing annealing techniques and image analysis, is described and applied to several different mesophase pitch systems.
