Structure of Vapour-deposited Carbon
Abstract
ALTHOUGH considerable information is available in the published literature on the effect of temperature and pressure of deposition on the microstructure and density of vapour-deposited carbon, only little has been reported on the pyrolytic graphite formed under these conditions from the crystallographic point of view. The purpose of this communication is to present X-ray results obtained in these laboratories from analysis of a series of experimental deposits produced over a range of high temperatures at a pressure of 50 mm. mercury. The perfection of three-dimensional crystallinity exhibited in some specimens produced at moderate deposition temperatures at this pressure is, to our knowledge, a new observation.
