Since the introduction of nitroglycerine as a blasting explosive by Nobel in 1867, enormous progress has been made in improving performance and reducing sensitivity of energetic materials. The introduction of nitrogen rich (N>60%) oxidizers such as 5,5′hydrazinebistetrazole (HBT) was one very important step in increasing the detonation performance and thermal stability of high explosives. Concurrently, the introduction of metal fuels which can react at high temperature attracted significant interest to improving combustion performance while also reducing the sensitivity of propellants and pyrotechnics. This is largely because metals such as aluminum, magnesium, titanium, zirconium and boron have very high volumetric (30-140 kJ.cm-3) and gravimetric energy density (10-50 kJ.g-1) compared with other chemical fuels. These fuels are also chemically stable solid simplifying storage and transport. Furthermore, they can be ignited and burned with oxidizers (air, metal nitrate, metal oxides) or water, to produce large amounts of heat, or hydrogen and heat.
