Abstract : Mass spectrometric studies of appropriate vapor species produced in the H2-BeO system under Knudsen conditions were carried out at temperatures up to 2426 K. Similar experiments were conducted with HCl-BeO system at 2723 K. Beryllia liner and beryllia gas inlet tube were used. Beryllium monohydroxide vapor was observed in measurable quantities in experiments on the H2-BeO system at 2426 K. From observations of other species appearing in the following equilibrium reaction BeO(g) + OH(g) = BeOH(g) + O(g) a tentative value for the heat of formation of BeOH(g) was evaluated to be -27.7 + or -5 kcal/mole. This is in agreement with the limiting value of -25 + or - 10 kcal/mole estimated by Hildenbrand et al, but at variance with the value of -40 + or - 5 kcal/mole reported by Greenbaum et al. (Author)
