Aerodynamic Levitation Reactor Studies of Fluorine Reactions with Refractory Ceramics
Abstract
The present work has placed emphasis on the detailed kinetic and mechanistic study of selected fluorine/ceramic reactions. The results of our program include work on fluorine reaction with Al2O3 (38, 39), B4C (33, 37), Re (61, 64), Gd (61, 65), LaB6 (37, 50, 61, 63) and LaB6-C, LaB6-MoSi2 composites (61, 63). One application of materials resistant to fluorine attack at high temperature is the HF chemical laser. Nickel and nickel alloys are useful in fluorine to ca. 1000K, but higher temperatures are required in CW HF lasers. Since the number of candidate materials decrease and fluorine corrosion rates increase with temperature it is useful to set upper bounds on the temperatures required for this application. Our analysis of this problem (61, 66) is presented. Given the temperature range of interest, the mechanisms by which fluorine gasifies solids limit the number of possible fluorine resistant materials.
