Abstract

PURPOSE: A pyrogenic composition that is prepared by adding a metal oxide as an auxiliary reaction accelerator and a water-soluble hydrazine inorganic acid salt as a reaction initiator to powdery iron, thus being suitably used for disposable body warmers because it generates heat by reaction with oxygen and water at high temperatures for many hours.
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 an alkali or alkaline earth metal as a reaction accelerator 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 hydrazine inorganic acid salt such as hydrazine hydrochloride to produce the objective composition that generates heat by reaction with water and oxygen. The preferable proportion of component AWD is 100:0.5W20:1W20: more than 0.5 by weight.
