Disclosed herein are compositions which are exothermic upon contact with oxygen and are self-steaming. The various described embodiments include compositions comprising: (a) a fuel component; (b) a water manager component; and (c) water. In one embodiment, the water manager component, has a mean particle size distribution of greater than about 250 microns. Alternatively or additionally, the ratio of the water manager component to the water is from about 0.001:1 to about 0.2:1, by weight. Alternatively or additionally, the fuel component comprises sponge iron. Alternatively or additionally, the composition comprises a volatile component. In yet another embodiment, articles comprising the compositions are described. Further, methods of making the compositions are described.
L'invention concerne des compositions qui sont exothermiques lorsqu'elles entrent en contact avec l'oxygène et autoproductrices de vapeur. Les divers modes de réalisation concernent des compositions qui comprennent : (a) un composant combustible ; (b) un composant de gestion de l'eau ; et (c) de l'eau. Dans un mode de réalisation, le composant de gestion de l'eau présente une distribution granulométrique moyenne supérieure à environ 250 microns. De plus ou dans une variante, le ratio du composant de gestion de l'eau et d'eau est compris entre environ 0,001:1 et environ 0,2:1 en poids. De plus ou dans une variante, le composant combustible comprend du fer spongieux. De plus ou dans une variante, la composition comprend un composant volatile. Dans un autre mode de réalisation, l'invention concerne les articles comprenant les compositions. L'invention concerne en outre les procédés de fabrication des compositions selon l'invention.
