A castable high-energy explosive composition comprising trinitrotoluene (TNT) and crystalline explosives of the RDX or HMX type as well as aluminum powder, and, optionally, flegmatizing agents and stablizers consisting of wax, lecithin and nitrocellulose (NC), is prepared by dispersing crystals of R
A castable high-energy explosive composition comprising trinitrotoluene (TNT) and crystalline explosives of the RDX or HMX type as well as aluminum powder, and, optionally, flegmatizing agents and stablizers consisting of wax, lecithin and nitrocellulose (NC), is prepared by dispersing crystals of RDX (or HMX) in water with wax, under heavy stirring and a temperature above the melting point of the wax, then adding aluminum powder, treated in order to tolerate water, to the dispersion, and then, optionally, cooling in order to separate the explosive as granules. A further step comprises melting and dispersing TNT in hot water under heavy stirring, optionally under the addition of wetted NC and lecithin, then reducing the temperature to below 80°C., and separating the solidifying, dispersed explosive droplets in the form of granules. The final step comprises mixing the products from the former steps in specific ratios so as to provide the final explosive compositions known by the name “Hexotonal”or “Octonal”, respectively. Alternatively, the mixtures of granules from the first two steps are melted together and cast on a drum, ribbon or plate, or the first two are combined in the same reactor before any part of the dispersed phases has solidified.

A process for the preparation of a castable, high-energy explosive composition comprising trinitrotoluene (TNT), RDX or HMX crystalline explosive and aluminum powder, comprising the following steps: A. dispersing wax and crystals of RDX or HMX in water with heavy stirring at a temperature above the melting point of the wax, then adding aluminum powder, treated in order to tolerate water, to the dispersion, thereby forming a dispersed mixture, cooling the mixture and separating it in the form of granules; and B. combining TNT with said dispersed mixture or with said granules, thereby obtaining said castable composition. A process according to claim 1, wherein the TNT of step B is separately melted and dispersed in hot water with heavy stirring, the temperature is reduced to below 80°C., granules of TNT are separated and are combined with the granules obtained from the dispersed mixture of step A. A process according to claim 8 or 9, wherein the montan wax is KP wax or S wax, separately or in admixture.
