Reactive multi-layer foil

<h2 id="uses">Uses</h2>
<p>The bonding process can be used in assembly of <a href="/facts/Electronics/E4JhgISq">electronics</a>, <a href="/facts/Die_attachment/Y52WABfR">die attachment</a> to <a href="/facts/Heatsink/ccIEdHnq">heatsinks</a> where high temperature stability is required (e.g. high-power <a href="/facts/LED/cMFILd4d">LEDs</a> or <a href="/facts/Concentrated_photovoltaics/zW6W1IRv">concentrated photovoltaics</a> <a href="/facts/Solar_panel/gufbEu8n">solar panels</a>, soldering together layers of <a href="/facts/Composite_armor/7ChAyoFA">composite armor</a> plates, bonding of large <a href="/facts/Sputtering/f6HGx4zz">sputtering</a> targets made of ceramics or <a href="/facts/Refractory_metal/WtGXfsVQ">refractory metals</a> where normal <a href="/facts/Indium/zRq3stVb">indium</a> based solders cannot be used, and other applications where a uniform joint over large area has to be created.<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a>
</p><p>The foil  can be used as a <a href="/facts/Pyrotechnic_heat_source/6wJP5CK0">pyrotechnic heat source</a>, a replacement of <a href="/facts/Potassium_chlorate/rARLS99c">potassium chlorate</a>/<a href="/facts/Iron/DkICCKIC">iron</a> pellets, for <a href="/facts/Thermal_battery/uf6BSl4M">thermal batteries</a>. It reacts faster than the conventional composition, reaches higher temperatures, and heat buffers of inert metal (e.g. steel) are needed to lower the peak temperature and prolong the heat delivery.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a>
They  can be also used as an electrically initiated <a href="/facts/Pyrotechnic_initiator/BfUDd0PM">pyrotechnic initiator</a>, e.g. to ignite <a href="/facts/Solid_propellant/K88ymXRy">solid propellants</a>, and in <a href="/facts/Decoy_flare/hPILe66r">decoy flares</a>. They can be employed in weapons as <a href="/facts/Reactive_material/yTVEyHwL">reactive materials</a>, enhancing the energy delivery to the targets by the projectiles or their fragments.
