The reactions of combustion products (CO, H 2 O) from the insensitive high explosive LX‐17 (92.5 wt% 1,3,5‐triamino‐2,4,6‐trinitrobenzene (TATB), 7.5 wt% Kel‐F 800 binder) with molten metal (75 a%Nd, 25 a% Fe) were studied, to determine their contribution to the energy release rate of deflagrating LX‐17, Kinetic data taken with gas mixtures of CO and H 2 O, and larger‐scale tests with LX‐17, showed that the reactions were slow and incomplete and that there was no significant contribution to the energy release rate. From the tests with JX‐17, the effective flame temperature and burn velocity were dependent on confinement of gas products. LX‐17 preheated to 500 K ‐ 510 K showed effective flame temperatures of 1100 K ‐ 1400 K and burn rates of 0.08–0.11 mm/s, depending on the extent of gas confinement by the molten metal.
