Combustion of derivatives of 1,5-diaminotetrazole

Combustion behavior of 1,5-diaminotetrazole (DAT), its salt with perchloric acid DAT $\cdot$ HClO$_4$, and coordination compounds (CCs) with Ni(II), Co(II), Cu(II), Cd, and Zn perchlorates in the interval of pressures from 0.1 to 36 MPa are studied. Despite the high energy content, DAT starts to burn only at extremely high pressures (above 24 MPa). Diaminotetrazole perchlorate possesses the maximum burning rate among all known organic perchlorates, and its combustion is described by a gas-phase model. The CC burning rates are also very high: the burning rate of [Cu(DAT)$_6$](ClO$_4$)$_2$ reaches the record-beating value (for laminar combustion) of 1670 mm/sec at a pressure of 34 MPa. CC combustion is also assumed to follow a gas-phase model. The influence of the metal nature on the combustion behavior of explosive coordination compounds is discussed.
