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, AlF3g Al2O3s yields 3AlOFg. Based on the assumption that equilibrium conditions exist, a preliminary heat of formation for AlOF at 298 deg K of -128 or - 11 kcalmole is obtained. A mathematical treatment of the BOF monomer data presented in the Fourth Quarterly Report AD0261026 indicates a value for the entropy at S298KBOFg of 53.1 or - 4.2 caldeg mole. The molecule HBO23 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.
