Preferred Label : polycrystalline graphite;
IUPAC acronym : HOPG;
IUPAC definition : A graphite material with coherent crystallographic domains of limited size regardless
of the perfection and preferred orientation (texture) of their crystalline structure.;
Scope note : the common use of the term polycrystalline graphite for polygranular graphite is in
line with this definition but may be inexact because usually all grains of polygranular
graphite are polycrystalline themselves. polycrystalline graphite can exhibit a random
orientation, more or less preferred orientation, or a highly oriented texture as in
some pyrolytic graphites there is no sharp transition, however, between the typical
polycrystalline texture and the single crystal-like texture of highly oriented pyrolytic
graphite (hopg).;
