Abstract: The invention is concerned with porous metal agglomerates suitable for use in metal fuels and consisting of combustible powders of nodular, flaky, irregular or acicular shape and preferably a mixture of aluminium and silicon although aluminium, aluminium alloy or aluminium mixed with silicon, magnesium or iron or alloys of these metals can be used. The powder is of 0 to 500 microns size range or a cut thereof and is granulated with a synthetic resin binder by build-up to a porous agglomerate having a size range of 100 to 2500 microns and an apparent density of between 0,4 and 1,1.

Abstract: An explosive grade aluminium composition comprises an admixture of aluminium powder and a subdivided carrier therefor having a bulk density less than or equal to that of the aluminium powder and wherein at least part of the powder adheres to the carrier, a coating agent being optionally included in the admixture to facilitate the adhesion of the powder to the carrier.
