Advanced solid rocket propellants with a low-pressure exponent and minimum signature comprise high- energy nitramine compounds such as hexogen and octogen. To achieve the desired processing conditions and increase the solid loading, the nitramine explosives are required with different grain size. The control of growth rate of crystals of nitramines by stirring, cooling and by crystal habit modifiers has been studied. The influence of these factors on crystal size distributions has been investigated and discussed. The results of both hexogen and octogen are compared.
