The thermite reaction is one your students will never forget. Flames, sparks, temperatures exceeding 2200 ºC and melted iron are all produced by this spectacular reaction. Thermite is a generic name given to a very high temperature reaction between a metal oxide and aluminum. The most common use of thermite is for fusion welding.
The demonstration of thermite has always been one you wish you could do, but don't because of the dangers in getting the reaction started. Recognizing this problem, Flinn Scientific has developed a special starting material called Thermite Igniting Sticks. These new igniting sticks are the most effective, safe, and controllable way to start a thermite reaction. Simply light the igniting stick with a match, place it into a pile of Thermit™, and watch the reaction take place. It's just that easy and safe. Teacher Demonstration Notes included. Enough materials are included to perform the demonstration seven times.
Concepts: Exothermic reactions, oxidation-reduction, thermite reaction.
Time Required: 20 minutes
Materials Provided: Thermit™ and thermite igniting sticks.
Note: Please remember that any demonstration where the reaction exceeds temperatures of 2200 ºC should always be done behind a safety shield and conducted in a fume hood or better yet outside. If you want to demonstrate a thermite reaction, this Flinn kit is your best choice.
