ABSTRACT
A device for determining the combustion heat of small mass for energetic materials (EMs) on the basis of 3D thermoelectric sensing technology was established. The combustion heat test results of dense ring energetic materials (TPNA, MNTIP, NTPA, OPTO, TTPA, and NTPNA) were - (2079.00 ± 2.6), - (3042.06 ± 6.2), - (2498.86 ± 8.2), - (1962.07 ± 8.3), - (2546.29 ± 3.5), and - (2792.87 ± 2.7) kJ • mol−1, respectively. The combustion heat test results of multi ring energetic materials (NPTTA, DNPOF, BNPBT, DNTI, BDNPBT, BDNPT, BTNBHT, AFAOT, and ATDAT) were - (3656.45 ± 3.5), - (3551.13 ± 4.6), - (4692.58 ± 25), - (3200.62 ± 8.3), - (5145.31 ± 33), - (3714.15 ± 11), - (7930.23 ± 6.5), - (2845.06 ± 2.5), and - (2000.18 ± 4.5) kJ • mol−1, respectively. The standard uncertainty of the test results ranges from 0.13% to 0.43%, indicating that the new combustion heat measurement device can be widely used to determine the combustion heats of small amounts of EMs.
