The Effective Nucleant during the Grain Modification of TNT with HNS,

Abstract

Small concentrations of 2,2',4,4',6,6'-hexanitrostilbene (HNS) have been shown previously to modify the grain structure of 2,4,6-trinitrotoluene (TNT). At the very low concentrations used, the character and properties of the effective nucleant proved difficult to study and so an enrichment process has been developed. It is found that the nucleant is not the HNS which was added originally, but a complex of composition (TNT)2. HNS which is formed during thermal cycling of the individual components. The pre-production and simple addition of complex just prior to casting has been shown to be a feasible alternative to the cycle-cast technique currently being employed. (Author)
