[0078] The exothermic composition is selected and prepared from the foregoing examples. As the silicon-containing mineral particles, volcanic soil (trass) (7% by weight of the total heat generating composition) was used, and as the metal particles, iron powder (72% by weight) was used. In addition, activated carbon (7 wt%) was used as the oxidizer, and 20% (14 wt%) of sodium chloride aqueous solution was used as the catalyst. These materials are mixed at room temperature and applied in a lamination method at a temperature of 100 to 130°C to make uniform formation.
[0079] In this embodiment, volcanic soil is used as the silicon-containing mineral particles, but other silicon-containing mineral particles such as zeolite may also be used. Furthermore, as the catalyst, an aqueous sodium chloride solution is used, but as described above, a compound containing a salt that oxidizes metal particles and water can also be used. In addition, as the oxidant, carbon compounds such as whit...
