spherical carbonaceous mesophase
A term which describes the
morphology
of
carbonaceous mesophase
which is formed in the
isotropic
pitch
matrix. The spherical
carbonaceous mesophase
usually has a lamellar structure consisting of flat aromatic molecules arranged in parallel layers which are perpendicular to the sphere/
isotropic
phase
interface
. On coalescence, this spherical
mesophase
loses its characteristic
morphology
and is converted to the
bulk mesophase
.
