Build-it no. 13: How to make ThermiteThis is a featured page



seeing as this is so easy to make, i wont even bother with the regular layout.

"The thermite reaction involves a mixture of iron oxide and aluminum that has been placed in a flower pot and covered with potassium permanganate. Some glycerin is poured over the potassium permanganate and eventually begins to react. When the iron oxide-aluminum mixture is ignited, a very vigorous reaction occurs and a molten metal can be seen dropping from the flower pot into a bucket of sand below. The reaction is extremely exothermic, a great deal of heat is given off. When the product of the reaction is examined a large piece of white hot iron has fallen into the sand at the bottom of the apparatus. This illustrates that aluminum is an extremely strong reducing agent and also that this reaction is very highly exothermic.The molten metal from the Thermite reaction is very hot. So hot, that Thermite has been used to weld railroad tracks together, and repair huge machinery that was a pain to take apart."

Mechie Edit: (I Made This In Our School Science Lab But Used Magnesium Ribbon As A Fuse, The Reaction Ended Up Destroying All Of The Pyrex Equipment, And We Got Free Iron!)
Mechie Edit: Potassium Permanganate Is Also Known As Potassium Manganate VII (7)
