Abstract
Abstract A fusible explosive composition comprises 40-90% by weight of a crystalline explosive with a high detonation velocity and 60-10% by weight of 2,4,6-trinitrotoluene, the crystalline explosive with a high detonation velocity consisting of 10-50% by weight of octogen, that is cyclotetramethylene-tetranitroamine and the remainder being hexogen, that is cyclotrimethylene-trinitroamine. The use of octogen causes a decrease in the melt viscosity and a decrease of deterioration, that is the increase in viscosity during successive fusions.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
31 words
An explosive composition according to claim 1, in which from 15 to 25% by weight of the crystalline explosive with a high detonation velocity is cyclotetramethylene-tetranitroamine and the remainder being cyclotrimethylene-trinitroamine.
Claim 2
Dependent Claim
21 words
An explosive composition according to claim 1, in which the particle size of the cyclotetramethylene-tetranitroamine is between 0 and 300 microns.
Claim 3
Dependent Claim
24 words
The composition according to claim 1, which comprises a co-crystallized mixture of cyclotrimethylene-trinitroamine and cyclotetramethylene-tetranitroamine in a weight ratio of from 60/40 to 85/15.
Claim 4
Dependent Claim
22 words
An explosive composition according to claim 4, in which said co-crystallized mixture is a by-product of the manufacture of cyclotetramethylene-tetranitroamine from hexamethylenetetraamine.
Claim 5
Dependent Claim
90 words
A process for molding an explosive composition, which comprises fusing at about 85* C a composition comprising from 40 to 90% of weight of a crystalline explosive with a high detonation velocity and from 60 to 10% by weight of 2,4,6-trinitrotoluene, from 10% to 50% by weight of said crystalline explosive being cyclotetramethylene-tetranitroamine and the remainder being cyclotrimethylene-trinitroamine, casting said fused composition into the desired shape, removing a portion of the cast material, repeating said steps of fusion and casting, each subsequent fusion being carried out at about 90* C.
Claim 6
Dependent Claim
20 words
The process according to claim 6 wherein said portion of the cast material which is removed is the upper portion.
Claim 7
Dependent Claim
27 words
The process according to claim 6 wherein said cyclotetramethylene-tetranitroamine and said cyclotrimethylene-trinitroamine of said explosive composition are precoated with fused 2,4,6-trinitrotoluene prior to fusion at 85* C.
Claim 8
Dependent Claim
24 words
The composition according to claim 1 which comprises 27% of 2,4,6-trinitrotoluene and 73% of said crystalline explosive wherein 10% by weight thereof is cyclotetramethylene-tetranitroamine.
Claim 9
Dependent Claim
23 words
The composition according to claim 1 which comprises 25% of 2,4,6-trinitrotoluene and 75% of said crystalline explosive wherein 15-20% by weight is cyclotetramethylene-tetranitroamine.
