EXOTHERMIC COMPOSITION Russian patent published in 2006 - IPC C09K5/00 C09K5/16 

FIELD: special compositions, chemistry.

SUBSTANCE: invention relates to chemical heat sources used for human protection against overcooling during prolonged works under condition of cold effect, in emergency and catastrophe in dry land and sea, and in medicinal heater and devices used for heating apparatus and equipments. The exothermic composition comprises iron powder, active carbon, neutral water-retaining sorbent, sodium chloride, water and substance for inhibition of evolution of gas representing iron oxide (III) monohydrate powder in the amount 0.1-1 weight%. The advantage of the exothermic composition involves the complete elimination of evolution of gas in storage of the composition-containing articles that prolongs the storage period of articles, retention of heat-evolving properties of articles, elimination the possibility for explosion of storing articles based on heat-generating compositions with using the process for oxidation of iron.

EFFECT: valuable properties of composition.
