The Condensation Coefficients of C2 and C3.
Abstract
The condensation coefficients of C2 and C3, the high temperature vapor species of carbon, were determined by using the isotopic exchange technique and a time-of-flight mass spectrometer. Two powder compacts of C12(s) and C13(s) were heated to 2663K in a tungsten Knudsen cell. Exchange reactions were studied by analyzing the vapor effusing from the Knudsen cell by a Time-of-Flight mass spectrometer. The condensation coefficient beta2 of C2 was evaluated from the steady-state concentration of C12C13(g). An expression relating the steady-state concentration of (C2(12)C(13)(g)+C(12)C2(13)(g)) and the condensation coefficient beta3 of C3 was derived. The expression was used to evaluate beta3. (Author)
