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 BeOg OHg BeOHg Og a tentative value for the heat of formation of BeOHg was evaluated to be -27.7 or -5 kcalmole. This is in agreement with the limiting value of -25 or - 10 kcalmole estimated by Hildenbrand et al, but at variance with the value of -40 or - 5 kcalmole reported by Greenbaum et al. Author
