ABSTRACT:
An insensitive high explosive is obtained by using a dicyandiamide (DCDA), ammonium nitrate (AN), guanidine nitrate (GN), ethylene diamine dinitrate (EDDN) eutectic melt binder in combination with ammonium perchlorate (AP) oxidizer, fine RDX (1 .mu.m to 10 .mu.m particle size), and aluminum metal as a fuel. The fine RDX particles improve performance, boosterability, and sensitivity. The inclusion of AP greatly improves air blast by adding oxygen to the reaction and insuring complete combustion of the ingredients. The aluminum extends the pressure pulse. The ratio of materials is formulated to obtain the lowest known processing temperature.
