Formulation Design and Performance Study of Titanium Hydride High-power Emulsion Explosive Based on Zero Oxygen Balance

Context: In order to obtain environmentally friendly emulsion explosives formulations with higher power, based on zero oxygen balance, formulations of titanium hydride (TiH)-high-power emulsion explosives were optimally designed. The results show that the zero oxygen balance formulation produces almost no toxic and harmful gases. The detonation temperature and detonation heat are increased. And the detonation volume decreases along with the increase in the content of TiH. Zero oxygen balance formulation can effectively enhance the explosive power of TiH-type high-power emulsion explosives compared to traditional formulations while improving its environmental friendliness and safety. This paper provides a basis for further development of the optimal brisance and environmentally friendly explosive formulations.

Methods: The principle of zero oxygen balance was applied to theoretically design the formulations of titanium hydride (TiH)-high-power emulsion explosives. To find a zero-oxygen balanced formulation with the best detonation performance, Hess's Law and Cast's Law were used to calculate the detonation parameters such as detonation heat and detonation temperature. Also, the B-W method was used to anticipate the detonation products.
