WebMar 19, 2024 · - Pyrolytic graphite is a very-high-density (2.2 gm/cm3), erosion-resistant, expensive form of graphite formed by the deposition of gaseous carbon on a substrate. This layer-by-layer deposition results in a highly anisotropic material that differs greatly from polycrystalline graphite.
