Abstract
Abstract A melt castable explosive composition not based on TNT is disclosed which consists essentially of about 10 to 20 weight percent of a matrix material having a melting temperature of about 60° to 100° C., up to about 0.5 weight percent of an emulsifying agent and up to about 20 weight percent aluminum powder, balance high explosive. The matrix material is ozokerite wax, ozokerite modified with carnauba wax, or a waxy polyethylene.
