To obtain the reaction characteristics of tetraethylammonium decahydrodecaborate （（C₂ H₅）₄N］₂B₁₀H₁₀，BHN-10） under explosion and shock， the reaction pathways and decomposition products of BHN-10 under shock were studied by electrically exploded plasma shock and explosive blast shock. Results show that the gaseous decomposition products of BHN-10 under electrically exploded plasma shock are organic combustible gases， such as carbon alkanes， alkenes， alkynes， and etc. BHN-10 has good stability under explosive blast shock. The shock wave of 25 GPa magnitude generated by explosive blast cannot promote the decomposition of BHN-10， while the explosion heat is a main factor leading to the reaction of BHN-10. The combustion of BHN-10 occurs under explosive blast shock after 8 ms， and the combustion appears from the central position， lasting for more than 200 ms. The mixture of HMX and BHN-10 has an accelerated diffusion speed of fireball under explosive blast shock， and its combustion time is equivalent to that of BHN-10.
