Abstract : Experimental mass spectrometric studies of high temperature vaporization and oxidation of graphite are described. Appearance potential curves for C1+, C2+, and C3+ are illustrated and discussed. Results from Langmuir studies of graphite vaporization of two types of graphite are discussed. Data for graphite oxidation by molecular oxygen above 2000K is presented. (Author)
