FIELD: chemical heat sources.
SUBSTANCE: exothermal composition comprises ferrum, initiator of oxidation reaction, moisture collecting sorbent, potassium chloride, and water. The oxidation reaction initiator is made of activated carbon the specific surface and specific volume of microscopic pores of which is equal to 500-700 m2/g and 0.15-0.25 cm3/g, respectively. The moisture-collecting sorbent is made of activated carbon the specific surface and specific volume of micro-pores of which is 1400-1600 m2/g and 0.7-1.0 cm3/g.
EFFECT: enhanced stability of composition.
