@X083@X05.@X0851 @X03 THERMIT
@X08Thermit is a fuel@X05-@X08oxodizer mixture that is used to generate tremendous
amounts of heat@X05.@X08 It was not presented in section 3@X05.@X0823 because it does not react
nearly as readily@X05.@X08 It is a mixture of iron oxide and aluminum@X05,@X08 both finely
powdered@X05.@X08 When it is ignited@X05,@X08 the aluminum burns@X05,@X08 and extracts the oxygen from
the iron oxide@X05.@X08 This is really two very exothermic reactions that produce a
combined temperature of about 2200 degrees C@X05.@X08 This is half the heat produced by
an atomic weapon@X05.@X08 It is difficult to ignite@X05,@X08 however@X05,@X08 but when it is ignited@X05,@X08
it is one of the most effective firestarters around@X05.@X08
MATERIALS
@X05_________
@X08powdered aluminum @X05(@X0810 g@X05)@X08
powdered iron oxide @X05(@X0810 g@X05)@X08
1@X05)@X08 There is no special procedure or equipment required to make thermit@X05.@X08 Simply
mix the two powders together@X05,@X08 and try to make the mixture as homogenous as
possible@X05.@X08 The ratio of iron oxide to aluminum is 50@X05%@X08 @X05/@X08 50@X05%@X08 by weight@X05,@X08 and
be made in greater or lesser amounts@X05.@X08
2@X05)@X08 Ignition of thermite can be accomplished by adding a small amount of
potassium chlorate to the thermit@X05,@X08 and pouring a few drops of sulfuric acid
on it@X05.@X08 This method and others will be discussed later in section 4@X05.@X0833@X05.@X08 The
other method of igniting thermit is with a magnesium strip@X05.@X08 Finally@X05,@X08 by
using common sparkler@X05-@X08type fireworks placed in the thermit@X05,@X08 the mixture
can be ignited@X05.@X08
