Mass-Spectrometric Studies of Graphite Vaporization at High Temperatures.
Abstract
The status of the equipment being assembled for a versatile high-pressure sampler-mass spectrometer system is reviewed. Schematic diagrams of the three carbon vapor sources being considered are shown. The first results of the cold-probe, hot-gas interaction study reveal the satisfactory operation of the time-of-flight method of temperature measurement, but indicate the presence of appreciable heat loss to the probe. A discussion of the continuum phenomena of mass separation and nucleation concludes with estimates of the condition under which they may become important in carbon vaporization. References are given for recent work on carbon and future research plans are outlined. (Author)
