Thermite is used in steel welding, fireworks shows, and hand grenades. It is the combination of a metal powder and a metal oxide which produce a reaction known for extremely high temperatures focused in a very small area for a short period of time. The 'active thermitic material' discovered in the World Trade Center dust was a combination of elemental aluminum and iron oxide, and is a form of thermite known as 'nano-structured super-thermite'.
