ABSTRACT:
A novel composite explosive comprised of conventional explosive material and a mixture of boron and at least one other metal is disclosed. The other metal must be capable of exothermically reacting with boron to produce intermetallic compound and an energy release of at least about 1.0 kcal/gm. In a preferred embodiment of the composite explosive, pellets of a stoichiometric mixture of boron and titanium are mixed with cyclotetramethylenetetranitramine (HMX). By mixing the boron and at least one other metal which forms an intermetallic compound with boron in an exothermic reaction wherein the heat energy release is at least about 1.0 kcal/gm and adding a conventional explosive material to the mixture, there is an improved method of forming a mass of hot or molten particles in an environment when the conventional explosive is detonated.
