Thermodynamics of Reactions Involving Light Metal Oxides and Propellant Gases

Abstract

An experiment was performed employing a specially designed high temperature electron bombardment-resistance furnace indicating the formation of AlOF as a result of the reaction, (T equals 2223 deg K), AlF3(g) + Al2O3(s) yields 3AlOF(g). Based on the assumption that equilibrium conditions exist, a preliminary heat of formation for AlOF at 298 deg K of -128 + or - 11 kcal/mole is obtained. A mathematical treatment of the BOF monomer data presented in the Fourth Quarterly Report (AD0261026) indicates a value for the entropy at S298KBOF(g) of 53.1 + or - 4.2 cal/deg/ mole. The molecule (HBO2)3 was studied in a transpiration experiment in which argon saturated with water is passed over heated boric oxide. The possibility that several species are present in the reaction mixture is considered, and a mathematical treatment of the data under these conditions is given.
