An extremely well graphitizing carbon with a high degree of optical anisotropy
(isochromatic areas of optical texture above about
) and which is characterized by a combination of the following properties which differ
significantly from those of regular coke
high real density, low reversible thermal expansion and low ash content combined,
in most cases, with low sulfur content.
