Abstract

An improved explosive composition is disclosed and comprises a major portion of an explosive having a detonation velocity between about 1,500 and 10,000 meters per second and a minor amount of a getter additive comprising a non-explosive compound or mixture of non-explosive compounds capable of chemically reacting with free radicals or ions under shock initiation conditions of 2,000 calories/cm² or less of energy fluence.

Claims

1. A composition of matter comprising a major portion of a metastable explosive capable of being detonated by a mechanical, electrical or thermal shock and having a detonation velocity between about 1,500 and 10,000 meters per second and a minor amount of a getter additive comprising a Group VIII metal nitroso halide.

2. The composition defined in claim 1 wherein said getter additive is present in an amount from 0.01 to 20 weight percent.

3. The composition defined in claim 1 wherein said getter is a Group VIII metal nitroso chloride.

4. The composition defined in claim 3 wherein said getter additive is ruthenium nitroso chloride.

5. The composition defined in claim 1 wherein said explosive is selected from trinitrotoluene, cyclotrimethylenetrinitramine, trinitrophenylmethylnitramine, triamino trinitrobenzene, pentaerythritol tetranitrate, diaminotrinitrobenzene, ammonium nitrate, nitroguanidine and diethyleneglycol dinitrate.

6. The composition defined in claim 1 wherein said explosive is trinitrotoluene and said getter is ruthenium nitroso chloride.
