Preferred Label : Brooks and Taylor structure;
IUPAC definition : 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.;
Scope 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.;
