Abstract
Abstract An explosive composition containing essentially of an intimate mixture of 15 TO 45% BY WEIGHT OF A PARTICULATE HIGH EXPLOSIVE FROM THE GROUP CONSISTING OF RDX (1,3,5-trinitro-1,3,5-triazacyclohexane) and HMX (1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane and mixtures thereof, 15 TO 50% BY WEIGHT OF AMMONIUM NITRATE, AND 20 TO 60% BY WEIGHT OF ETHYLENEDIAMINE DINITRATE; WHEREIN THE WEIGHT RATIO OF AMMONIUM NITRATE TO ETHYLENEDIAMINE DINITRATE IS FROM 1:2.5 TO 1.5:1, RESPECTIVELY, AND PARTICULARLY ABOUT 1:1. These explosive compositions provide an unexpectedly high explosive output with a relatively low content of RDX and/or HMX, and an equivalent output with much less RDX than conventional explosive compositions consisting of mixtures of RDX with AN and/or TNT.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
81 words
An explosive composition consisting essentially of a mixture of 15 to 45% by weight of a particulate high explosive selected from the group consisting of 1,3,5-trinitro-1,3,5-triazacyclohexane and 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane, and mixtures thereof; 15 to 50% by weight of ammonium nitrate; and 20 to 60% by weight of ethylenediamine dinitrate; wherein the ammonium nitrate and the ethylenediamine dinitrate are present in the weight ratio of from 1:2.5 to 1.5:1, respectively, as an intimate mixture of which the major portion is obtained by cosolidification.
Claim 2
Dependent Claim
81 words
An explosive composition consisting essentially of a mixture of 15 to 45% by weight of a particulate high explosive selected from the group consisting of 1,3,5-trinitro-1,3,5-triazacyclohexane and 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane, and mixtures thereof; 15 to 50% by weight of ammonium nitrate; and 20 to 60% by weight of ethylenediamine dinitrate; wherein the ammonium nitrate and the ethylenediamine dinitrate are present in the weight ratio of from 1:2.5 to 1.5:1, respectively, as an intimate mixture of which the major portion is obtained by cosolidification.
Claim 3
Dependent Claim
25 words
The explosive composition of claim 1, wherein substantially all of said ammonium nitrate and ethylenediamine dinitrate are present as an intimate mixture obtained by cosolidification.
Claim 4
Dependent Claim
36 words
The explosive composition of claim 2, wherein the ammonium nitrate and ethylenediamine dinitrate are present in essentially the eutectic weight ratio of about 1:1 as an intimate mixture obtained by cosolidification of a molten mixture thereof.
Claim 5
Dependent Claim
53 words
The explosive composition of claim 3, obtained by heating the mixture in an inert carrier liquid to a temperature above the melting point of the eutectic mixture of ethylenediamine dinitrate and ammonium nitrate, and cooling the mixture to solidify said eutectic mixture largely as a coating on the particles of the high explosive.
Claim 6
Dependent Claim
19 words
The explosive composition of claim 3, wherein the high explosive amounts to about 40% by weight of the mixture.
Claim 7
Dependent Claim
12 words
The explosive composition of claim 1, wherein the high explosive is 1,3,5-trinitro-1,3,5-triazacyclohexane.
Claim 8
Dependent Claim
9 words
A cast explosive of the composition of claim 1.
Claim 9
Dependent Claim
9 words
A pressed explosive of the composition of claim 1.
