Term: polycrystalline graphite
https://doi.org/10.1351/goldbook.P04723

Definition:
A graphite material with coherent crystallographic domains of limited size regardless of the perfection and preferred orientation (texture) of their crystalline structure.

Note: The common use of the term polycrystalline @G02684@ for @P04731@ is in line with this definition but may be inexact because usually all grains of @P04731@ are polycrystalline themselves. Polycrystalline @G02684@ can exhibit a random orientation, more or less preferred orientation, or a highly oriented texture as in some @P04964@ There is no sharp transition, however, between the typical polycrystalline texture and the 'single crystal-like' texture of @H02823@ (HOPG).
