Abstract
Industrial samples of coal tar pitch are investigated by means of Raman spectroscopy. On the basis of the analysis, relationships are established for the physicochemical properties of various pitch samples. Increase in the softening temperature is associated with the growth of graphite-like crystallites on account of increase in the proportion of edge defects. An inverse correlation is found between the tangent of the inclination of the pitch’s basic spectral line and its composition (in terms of pitch grades).
