Random Pyrolytic Carbon


THE unique properties of pyrolytic carbon have made it useful for many high-temperature applications. Because of the anisotropy of the physical and mechanical properties of the individual crystallites, the properties of macroscopic specimens depend strongly on their preferred orientations. For certain applications, such as thermal shields, high anisotropy may be desirable; on the other hand, other applications (those requiring good thermal shock resistance) would benefit from isotropic properties resulting from a random structure.
