<p>PURPOSE:A safe pyrogen having a high calorific value per unit time and prolonged heat production time, free from danger or toxicity, prepared by incorporating an ion-containing liquid and metallic powder, with a noble metal catalyst, e.g. Pt or pd. CONSTITUTION:A pyrogen comprising (A) a mixture of (a) powder of simple metal having the ionization tendency stronger than hydrogen or a substance containing it, and (b) an ion-containing liquid and (B) a noble metal catalyst, e.g. Pt, Pd, Rh, or Ag alone or in combination. The catalyst (B) is useful for reducing the oxygen adsorbed on the porous gas electrode immediately without dissociation as shown in the reaction formula to accelerate the decomposition of HO2<->. The shortage of the calorific value per unit time is thus avoided. USE:Pyrogenic hot fomentations and disposable body warmers.</p> |
