A continuous anisotropic phase formed by coalescence of mesophase
spheres. Bulk mesophase
and is deformable in the temperature range up to about
and transforms into green coke
by further loss of hydrogen or low-molecular-weight
species. This bulk mesophase
can sometimes be formed directly from the isotropicpitch
without observation of intermediate spheres.
