Term: pyrolytic graphite
https://doi.org/10.1351/goldbook.P04964

Definition:
A graphite material with a high degree of preferred crystallographic orientation of the c-axes perpendicular to the surface of the substrate, obtained by graphitization heat treatment of pyrolytic carbon or by chemical vapour deposition at temperatures above 2500 K.

Note: 'Pyrographite', a synonym for pyrolytic @G02684@, was introduced as a trademark and should not be used as a term. Hot working of pyrolytic @G02684@ (by heat treatment under compressive stress at temperatures above 3000 K) results in @H02823@ (HOPG).
