The structure of the anisotropic spheres which precipitate from
isotropic
pitch
during
pyrolysis
. The structure of the spheres consists of a lamellar arrangement of aromatic molecules in parallel layers which are perpendicular to the polar axis of the sphere and which are perpendicular to the
mesophase
-
isotropic
phase
interface
.
Note:
The term Brooks and Taylor structure is recommended to describe the particular lamellar
morphology
of the spherules most commonly precipitated from pyrolysed
pitch
. The term honours the workers who first recognized the significance of
carbonaceous mesophase
to carbon science and technology and who first defined this spherical
morphology
. The term Brooks and Taylor structure does not cover all structures found in the spherical
mesophase
, because other lamellar arrangements have been observed.
