Investigation of Carbon Vapor Pressure at Very High Temperatures and Pressures with the Aid of Laser Heating

Abstract

For several decades the behavior of carbon and carbonaceous materials has been observed with unvarying interest. Well known are two polymorphous modifications of carbon, namely, graphite and diamond, each possessing unique physicochemical properties which make them attractive for extensive utilization in numerous industries.The history of carbon studies at high temperatures and pressures produced quite a few examples of ingenious experimental techniques and experimenter's skill, however, many of those studies only resulted in the emergence of new, hard-to-solve problems. This is precisely the case with the melting and vaporization of graphite.
