This article reports on a new family of detonating compositions in which ammonium dinitramide (ADN) is used as an explosive oxidizer, and red phosphorus (Pr) or titanium hydride (TiH2) as fuels. At optimized ADN/fuel ratios, these compositions have typical explosion heats higher than 7 kJ/g, detonation velocities in 3 mm diameter tubes ranging from 1.2 to 2.0 km/s at ∼40 % of their theoretical maximum density, with a run to detonation distance between 20 and 40 mm. Both compositions are insensitive to electrostatic discharge, but are very sensitive to impact and friction, ADN/Pr mixtures being the most sensitive to these stress. The shockwave released by the reaction of these materials, efficiently initiates the detonation of high explosives such as pentaerythritol tetranitrate (PETN) or hexogen (RDX). In view of these characteristics, ADN‐based detonating compositions must be considered as “green” substitutes for primary explosives containing heavy metals.

Dinitramide铵的新引爆成分

本文报道了一种新的起爆组合物系列,其中二硝酰胺铵(ADN)被用作爆炸性氧化剂,红磷(P r)或氢化钛(TiH 2)被用作燃料。在优化的ADN /燃料比下,这些成分的典型爆炸热高于7 kJ / g,直径3 mm的管中的爆炸速度为理论最大密度的〜40%,范围为1.2至2.0 km / s,并且可以爆炸。 20至40毫米之间的距离。两种组合物均对静电放电不敏感,但对冲击和摩擦非常敏感,ADN / P r混合物对这些压力最敏感。这些材料反应释放的冲击波有效地引发了高爆炸药的爆炸,例如季戊四醇四硝酸盐(PETN)或六原体(RDX)。鉴于这些特性,必须将基于ADN的起爆成分视为含有重金属的初级炸药的“绿色”替代品。
