“…Two phases were found in the case of thermal decomposition of lead azide in the temperature range T = 423-473 K without application of mechanical loads [6]. One phase was identified as a tetragonal deformed cubic lattice; the second phase may contain the basic lead azides and other oxygen-containing compounds in accordance with the generalized formula PbN 3.5 (OH) x .…”

“…One phase was identified as a tetragonal deformed cubic lattice; the second phase may contain the basic lead azides and other oxygen-containing compounds in accordance with the generalized formula PbN 3.5 (OH) x . Stammler et al [6] assumed that further decomposition of lead azide is possible only in the presence of moisture. The activation energies in this temperature range measured in [6] were 335 and 420 kJ/mole for the original LA and these phases, respectively.…”

“…In the high-temperature region T = 535-570 K, LA thermal decomposition proceeds with a high velocity and with the activation energy E = 211-232 kJ/mole [5,6]. In the case of mechanical fracture of a partly decomposed LA specimen, the boundary between lead and azide can be seen on the fracture boundary, but no discrete nuclei are observed.…”

Decomposition of lead azide (LA), pentaerythrite tetranitrate (PETN), and a laminate system composed of these substances under vibrational loading is considered. Sensitivity of these substances to impact and vibrations is determined. Sensitivity of the LA + PETN laminate system to vibrational loading, which is characterized by the degree of decomposition, is substantially higher than that of PETN, but lower than that of LA. Specific features of the mechanism of decomposition of these substances at moderate values of vibration parameters and temperatures of specimen heating are discussed.

Copper Bis(1‐methyl‐5‐nitriminotetrazolate): A Promising New Primary Explosive

2007

View full text Add to dashboard Cite

Copper bis(1‐methyl‐5‐nitriminotetrazolate) (1) was synthesized and investigated as a new primary explosive. Compound 1 was obtained by dehydration of diaquabis(1‐methylnitriminotetrazolato)copper(II) dihydrate (2) or diaquabis(1‐methylnitriminotetrazolato)copper(II) (3) at 120 °C. Complexes 2 and 3 are easily formed by the reaction of 1‐methyl‐5‐nitrimino‐1,2,3,4‐tetrazole (4) with copper(II) nitrate in aqueous solution in high yields. Single crystals of 1 were obtained by recrystallization from dry methanol, whereas wet methanol favors the yield of diaquabis(1‐methyl‐nitriminotetrazolato)copper(II) dimethanolate (5). Compound 1 was characterized by using single‐crystal X‐ray diffraction, IR spectroscopy, elemental analysis, and differential scanning calorimetry (DSC). The sensitivities were investigated by using the BAM drophammer and friction tests, and the heat of formation was calculated on the basis of electronic energies at the B3LYP/SDD level of theory. Compound 1 shows an impact sensitivity that is five times higher and a friction sensitivity that is ten times lower than that of lead azide, which is appropriate. In addition, the long‐term stability of 1 at higher temperatures was tested by using isothermal safety calorimetry (TSC). Compounds 2 and 3 were characterized by single‐crystal X‐ray diffraction, IR spectroscopy, elemental analysis, DSC, bomb calorimetry, and BAM sensitivity tests. In addition, compound 5 was characterized by single‐crystal X‐ray diffraction and elemental analysis. The dehydration of 2 was determined by using thermal gravimetry (TG) to occur by the loss of crystal water in one discrete step. (© WILEY‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
