A Chemical Deep Dive<\/h3>\n<p>In a nutshell, the Thermite Reaction is all about <strong>aluminum&#8217;s incredible power to &#8220;steal&#8221; oxygen<\/strong>.

On the other hand, <strong>iron oxide<\/strong> is iron that is already holding onto oxygen. When you provide an ignition source, the aluminum forcefully strips the oxygen away from the iron. As a result, the iron is separated as &#8220;pure iron,&#8221; and the aluminum transforms into aluminum oxide.<\/p>\n<p>During this &#8220;theft of oxygen,&#8221; a massive amount of energy is released. This is called an <strong>exothermic reaction<\/strong>, and the temperature can soar to <strong>over 2,000\u00b0C<\/strong>! This ultra-high temperature is so effective that it has been used as a &#8220;real-world technology&#8221; for welding giant ship parts and, even today, for joining railway tracks.<\/p>\n<h3>Putting it into Practice!
