ABSTRACT:
An exothermic composition, enclosed in a container at least part of which is gas-permeable, generates heat in the presence of air. The exothermic composition includes a water absorber having a water absorptive ability reversibly variable with temperature variations. The water absorber releases adsorbed water, at above a predetermined temperature, to increase free moisture around a metal powder, thereby retarding the exothermic reaction.
