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.

An insensitive high performance explosive composition comprising:
- a eutectic melt comprising dicyandiamide (DCDA), ammonium nitrate (AN), guanidine nitrate (GN), ethylene diamine dinitrate (EDDN);
- 1,3,5-trinitro-1,3,5-triaza-cyclohexane (RDX) having a particle size in the range from about 1 .mu.m to about 10 .mu.m;
- ammonium perchlorate (AP);
- and
- a reactive metal.
An insensitive high performance explosive composition comprising:
- a eutectic melt comprising dicyandiamide (DCDA), ammonium nitrate (AN), guanidine nitrate (GN), ethylene diamine dinitrate (EDDN), wherein the DCDA, AN, GN, and EDDN forming the eutectic melt are present in the following weight ratio:
- 20% to 25% DCDA, 35% to 40% AN, 10% to 15% GN, and 25% to 30% EDDN, and wherein the eutectic melt represents from about 20% to about 50% of the explosive composition;
- 1,3,5-trinitro-1,3,5-triaza-cyclohexane (RDX) having a particle size in the range from about 1 .mu.m to about 10 .mu.m;
- ammonium perchlorate (AP) present in the explosive composition in the range from about 10% to about 60%, by weight;
- and
- aluminum present in the explosive composition in the range from about 10% to about 45%, by weight.
