Stability of BHN-10 under Explosion and Electric Detonation Shock Waves.

To explore the stability of high-energy fuels under strong shock wave effect and simulate the practical enviroment, the explosion and electric detonation shock methods were used to study the stability of boron hydride salt (BHN-10) under shock effect as well as the gas and solid products produced by the decomposition of the boron hydride salt. Moreover, HMX was introduced in BHN-10 to investigate the effect on the decomposition efficiency of BHN-10. The results show that BHN-10 has good stability to the impact of detonation shock generated by single explosive. The shock wave of 1.0 GPa magnitude generated by single explosive detonation cannot promote the decomposition of BHN-10. BHN-10 has relatively low stability under the shock of electric detonation. The interaction of shock and heat generated by the plasma electric detonation method result in the decomposition of BHN-10, and the organic flammable gas products with high calorific value contain triethylamine, nitrile, paraffin, olefin or alkyne. After adding HMX into the BHN-10, the length of the carbon chain of the gas products is shortened and less than 4 carbon atoms except for triethylamine. The addition of HMX can greatly improve the decomposition efficiency of the BHN-10 fuel, and generate low carbon chain flammable gases with a higher proportion. Under the N₂ atmosphere, the solid decomposition products of BHN-10 contain C₆₀ and orthorhombic B₁₂H₁₆. Under the air atmosphere, the solid decomposition products are C₆₀, B₁₂H₁₆, B₂O₃ and boric acid. After adding HMX, the solid products from the decomposition of the BHN-10 are mainly amorphous phases of C and B elements. [ABSTRACT FROM AUTHOR]
