STUDY OF ROCKET ENGINE EXHAUST PRODUCTS

Abstract

The Knudsen torsion effusion technique was employed in the temperature range 440 to 680 C to obtain the following thermodynamic functions for BeF2: heat of sublimation of 66.13 ! 0.71 kcal; heat of vaporization of 53.05 ! 0.55 kcal; and entropy of sublimation of 54.3 ! 0.9 e.u. In the temperature range 550 to 610, the average molecular weight of the effusing species as determined from torsion and gravimetric experiments, indicated no association of BeF2. The calculated molecular weight of effusing gases was 44.7 ! 2.0. The molecular weight of BeF2 is 47.0. (Author)
