Vaporization Kinetics and Thermodynamics of Graphite Using the High Pressure Mass Spectrometer.

Abstract

The report describes efforts to characterize the vaporization of graphite, with present emphasis on observing equilibrium ratios of carbon clusters at temperatures exceeding 3000K. An all-carbon Knudsen cell, described earlier, was used with a modified current concentrator and an improved viewing arrangement for the pyrometer. The report describes the work accomplished in testing the modified apparatus and the results of the first species-ratio measurements carried out in the previous quarter. The research is for the purpose to design a mass spectrometer. (Author)
