A @G02687@ with a high degree of preferred crystallographic orientation of the c-axes perpendicular to the surface of the substrate, obtained by @G02692@ of @P04963@ or by chemical vapour deposition at temperatures above \(2500\ \text{K}\).
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 \(3000\ \text{K}\)) results in @H02823@ (HOPG).
