Abstract
PURPOSE: A pyrogentic composition that is prepared by adding a metal oxide as an auxiliary reaction acceleraor and a water-soluble salt from organic base and inorganic acid as a reaction initiator to iron, thus being suitably used for disposable body warmers because it reacts with water and oxygen to rapidly generate heat rapidly with high temperature for many hours kept.
CONSTITUTION: (A) powdery or particulate iron and (B) a chloride or sulfate of metal, preferably of metal having a higher ionization tendency than iron such as alkali or alkaline earth metal, are used as the effective components and they are combined with (C) a metal oxide, preferably an oxide of copper or manganese, as an auxiliary reaction accelerator and (D) a water-soluble salt from organic base and inorganic acid such as methylamine hydrochloride to produce the objective pyrogenic composition that generates heat by reaction with water and oxygen. The proportion of components A through D is 100:0.5W20:1W20: more than 0.5 by weight preferably.
