Comparison on ignition and combustion of AlMgB composite fuel and B fuel

Dual-core–shell structure B@LiF@AP with multi-effect synergies to improve processibility and energy release characteristics of B

“…4a, in the ignition experiment, the time required from the generation of electric current to a sudden increase in the light signal is defined as the ignition delay time of this sample. Then, the ignition energy of the sample was calculated using eqn (4): 16,41 …”

“…[8][9][10][11][12][13][14] Boron-based fuel-rich propellants have the highest specic impulse between them because boron (B) has a high caloric value and high-density performance characteristics. [15][16][17][18] However, boric acid (H 3 BO 3 ) and boron oxide (B 2 O 3 ) on the surface of B and combustion product B 2 O 3 cause many problems (ignition, combustion and processibility) during the application of B. 17,[19][20][21] Owing to the extremely different melting point (450 °C) and boiling point (1860 °C) of B 2 O 3 , there is a layer of liquid B 2 O 3 during B combustion.…”

Performance enhancement strategy for tetrazoles based on nitrogen–boron bonds

“…In the laser ignition delay experiment, a three-color PMT detector was used to detect the laser and visible signals. 31,32 Due to the stability and detonation properties, mono-tetrazolyl borane 7 exhibited better application prospects than compounds 5 and 6 and was the subject of our subsequent research. According to Fig.…”

“…The ignition delay time of 7 was measured by the analysis of the radiation signals from the PMT. 31,32 The density was measured by AccuPyc II 1345 gas displacement pycnometry system (Micromeritics, American). TG-DSC-FTIR-MS technique made by ourselves under a heating rate of 10 °C min −1 with Air.…”
