Klapötke, Thomas M.; Cudzilo, Stanislaw und Trzcinski, Waldemar A. (2022): An Answer to the Question about the Energetic Performance of TKX-50. In: Propellants Explosives Pyrotechnics, Bd. 47, Nr. 6

Abstract

Some of the relevant detonation performance parameters of TKX-50 were re-determined. The enthalpy of formation was obtained from the measured heat of combustion to be Delta H-f degrees (TKX-50(s))= + 213.4 +/- 1.2 kJ nnol (-1) The heat of detonation was measured to be 4650 +/- 50 kJ kg(-1). The detonation velocity of a TKX-50/wax mixture (97:3) at a density of 1.74 gcm(-3) was found experimentally to be 9190 m s(-1). Using the experimentally obtained enthalpy of formation for TKX-50 of +213.4 kJ mol(-1) and the experimentally determined solid-state density at room temperature of 1.887 gcm(-3) (TMD), the computed performance parameters for TKX-50 at its theoretical maximum density at room temperature was calculated to be as follows: VoD = 9642 ms(-1), p(C-J) = 37.0 GPa and Q(det) = 4770 kJ kg(-1).
