Pressure Profiles

Detonation pressure profiles in TNT/RDX and its mixtures with aluminum powders of different particle size have been studied with Manganin piezoresistance gauge. The measured detonation pressure accorded with the calculated detonation pressure. The results show that micrometer aluminum powders reacted with detonation at times of 0.5μs after the peak pressure. Aluminum powders did not react in the detonation zone, and introducing aluminum into explosive would reduce the detonation pressure. Compare with micrometer aluminum powders, nanometer aluminum powders reacted with detonation product more quickly.

Hydrolysis Of

In the present investigation, the Al-C-KCl composite powders were prepared by a ball milling processing in an attempt to improve the hydrogen evolution capacity of aluminum in water. The results showed that the hydrogen generation reaction is affected by KCl amount, preparation processing, initial aluminum particle size and reaction temperature. Increasing KCl amount led to an increased hydrogen generation volume. The use of aluminum powder with a fine particle size could promote the aluminum hydrolysis reaction and get an increased hydrogen generation rate. The reaction temperature played an important role in hydrogen generation rate and the maximum hydrogen generation rate of 44.8 cm3 min-1g-1of Al was obtained at 75oC. The XRD results identified that the hydrolysis byproducts are bayerite (Al(OH)3) and boehmite (AlOOH).
