Estimating the term…
The present invention relates to a heating device comprising a heat generating portion composed of a mixture of at least of ferric oxide, cupric oxide and trilead tetroxide powder and powder of silicon and/or silicon-iron alloy, a firing portion disposed contiguous to said heat generating portion and constituted by mixing boron or aluminum powder with at least one of ferric oxide, cupric oxide, barium peroxide and strontium peroxide powder, and an igniting portion situated adjacent to said firing portion and composed of a mixture of red phosphorus and potassium chlorate which is ignited by frictional heat or sparks of a flint. This heating device is capable of quick and easy heating of an object to be heated with no need of using any extraneous heating means. The invention also provides an instantaneous heater utilizing the heating device.
A heating device comprising a heat generating portion comprising a mixture of at least one of ferric oxide, cupric oxide and trilead tetraoxide powder and powder selected from the group consisting of silicon, silicon-iron alloy and mixture thereof, a firing portion disposed contiguous to said heat generating portion and comprising of a mixture of a member selected from the group consisting of boron, aluminum powder and mixture thereof and at least one of ferric oxide, cupric oxide, barium peroxide and strontium peroxide powder, and an igniting portion situated adjacent to said firing portion and said igniting portion generating frictional sparks of a flint to set off said firing portion.
