EP0363494B1 — Heat-generating member

USPTO Abstract

This invention relates to a heat-generating member consisting of a heat-generating section (1), an igniting section (2) and a fire striking section (3). The heat-generating section is prepared from a mixture of at least one powder selected from the group consisting of the powders of ferric oxide, cupric oxide and trilead tetraoxide with the powder of silicon and/or an alloy of silicon and iron. The igniting section is prepared by mixing boron and/or aluminium powder with at least one member selected from the group consisting of ferric oxide, cupric oxide, barium peroxide and strontium peroxide. The fire striking section includes either a fire striking agent consisting of a mixture of red phosphorus with potassium chlorate, or a flint. This section strikes fire upon friction. The heat-generating member can be ignited and generate heat easily and rapidly and so it can be utilized for a liquid or solid heater as a compact and portable heat-generating member.
