Abstract : The ideal thermodynamic properties and composition for the combustion products of Be and air are presented for pressures from 10 to the -6th power to 100 atm and temperatures from 1000 to 6000 K. The chemical species considered were gaseous N2, N, NO, O2, O, Be, BeO, (BeO)2, (BeO)3, (BeO)4 and BeO (solid and liquid). The contribution of CO2 and Ar in air were ignored. The composition of the reactants corresponds to 0.422 Be + 0.2115 O2 + 0.7885N2 in moles. The properties calculatedARE FOR AN IDEAL MIXTURE OF PURE GASES, LIQUIDS, AND SOLIDS. The thermodynamic properties are tabulated and presented as a Mollier chart. The compositions are reported in chart form. The boiling point, percentage of BeO condensation, and the adiabatic flame temperature for various pressures are given. The effects of melting, vaporization, and dissociation are included in the Mollier diagram.
