Thermite is a chemical used mainly to destroy pipes, file cabinets, and
|
|||
|
|
heavy equipment. Thermite is also used for temporary welding, but it has no
|
|||
|
|
finesse, and is not very strong. Now the part you've all been waiting for...
|
|||
|
|
the formula for it.
|
|||
|
|
|
|||
|
|
Thermite is composed of magnetic iron flakes and aluminum powder. Thermite
|
|||
|
|
may be obtained as a manufactured item or may be improvised for use in welding
|
|||
|
|
machinery parts together and burning holes in metal structures. The thermite
|
|||
|
|
reaction is initiated by strong heat and cannot be directly ignited with a
|
|||
|
|
match, lighter, or fuse. These igniters (found later in this file) are high
|
|||
|
|
heat reactions that are capable of producing the heat needed to set off the
|
|||
|
|
thermite reaction.
|
|||
|
|
|
|||
|
|
Thermite is very safe to handle and transport because of its high ignition
|
|||
|
|
temperature. It burns well in cold and windy weather. Thermite will
|
|||
|
|
penetrate a sealed container and then ignite the contents. It may be easily
|
|||
|
|
improvised if aluminum and magnetic iron flakes of the appropriate size can be
|
|||
|
|
found.
|
|||
|
|
|
|||
|
|
Materials and equipment:
|
|||
|
|
|
|||
|
|
Aluminum powder (no coarser than ground coffee)
|
|||
|
|
Iron oxide flakes (Fe3O4 - same size as aluminum)
|
|||
|
|
Spoon or cup for measuring
|
|||
|
|
Jar or can with tight fitting lid
|
|||
|
|
Cardboard can with tight fitting metal ends
|
|||
|
|
|
|||
|
|
Preparation:
|
|||
|
|
|
|||
|
|
1. Place three (3) parts by volume of Iron Oxide (Fe3O4) and two (2) parts
|
|||
|
|
by volume of aluminum powder into the jar. Fill it about 2/3 full of
|
|||
|
|
the mixture so that there is enough room for mixing.
|
|||
|
|
2. Tighten the lid on the jar, turn the jar on its side and slowly roll
|
|||
|
|
until the two (2) powders are completely mixed. If you have the time,
|
|||
|
|
then mix small amounts of the powders in a mortar and pestle, which
|
|||
|
|
will take hours if you do correctly. No matter how you mix the
|
|||
|
|
materials, once it is mixed it will last for months without losing
|
|||
|
|
effectiveness.
|
|||
|
|
|
|||
|
|
Application:
|
|||
|
|
|
|||
|
|
Thermite is used to attack metallic targets such as transformers, electric
|
|||
|
|
motors, phone areas, gears, boilers, gas storage tank farms, and
|
|||
|
|
pipelines. This method produces a quantity of molten metal that streams
|
|||
|
|
out of the bottom of the unit. On contact with the target, the molten
|
|||
|
|
metal will cut through the outer metal casing and pour molten metal on the
|
|||
|
|
contents in it. Thermite is not recommended for use on moderate or wooden
|
|||
|
|
structures or other applications where a constant, persistant flame is
|
|||
|
|
required.
|
|||
|
|
|
|||
|
|
In order to penetrate a steel plate with the minimum quantity of thermite,
|
|||
|
|
the bulk of the ignited thermite must be held away from the target during
|
|||
|
|
the initial combustion period. This minimizes conductive heat loss (from
|
|||
|
|
the thermite to the target) during this period and results in the thermite
|
|||
|
|
attaining maximum combustion temperature. When that temperature is
|
|||
|
|
reached, the thermite is dropped molten onto the target, and a hole is
|
|||
|
|
burned to the innards of the target.
|
|||
|
|
|
|||
|
|
Cut a cardboard can (having metal ends) into two (2) equal sections.
|
|||
|
|
Example types of cardboard cartons are AJAX and BON AMI.
|
|||
|
|
|
|||
|
|
One section of the can must be trimmed to a height of two (2) inches as
|
|||
|
|
shown.

------------
|
|||
|
|
|
|||
|
|
The other section is filled 2/3 full with thermite. The thermite is
|
|||
|
|
covered with one of the igniters mentioned later in the file.
|
|||
|
|
Put the vented section (illustrated above) face down on the target.
|
|||
|
|
The metallic end faces up. The section filled with thermite is placed on
|
|||
|
|
top of the piece already in place. Both metal ends are now touching.
|
|||
|
|
|
|||
|
|
After ignition, the thermite burns a hole through the steel plate,
|
|||
|
|
dropping extremely hot particles of molten slag into the target.
|
|||
|
|
|
|||
|
|
Welding:
|
|||
|
|
|
|||
|
|
A different method is employed to weld materials together. Instead of
|
|||
|
|
being mounted several inches above the target, the ajax container is going
|
|||
|
|
to be placed directly on the target, as illustrated.

The heat is conducted from the iron oxide onto the two (2) plates and a

Igniter:
|
|||
|
|
|
|||
|
|
Powdered Aluminum/Sulfur Pellets:
|
|||
|
|
|
|||
|
|
This igniter consists of finely powdered aluminum, sulfur and starch which
|
|||
|
|
have been thoroughly mixed and shaped into hardened cylindrical pellets.
|
|||
|
|
The pellet is drilled with a small size drill bit, filled with gunpowder,
|
|||
|
|
and can be ignited with a match or a fuse.
|
|||
|
|
|
|||
|
|
Material:
|
|||
|
|
|
|||
|
|
Finely powdered Aluminum (no coarser than powdered flour)
|
|||
|
|
Finely powdered Sulfur (same consistency)
|
|||
|
|
Finely powdered Starch (same consistency)
|
|||
|
|
Water
|
|||
|
|
Cylindrical tube about 4 inches long and 3/4 inch inside diameter
|
|||
|
|
made of Metal, Wood, Glass, or Plastic.
|
|||
|
|
Rod which fits into the above tube.
|
|||
|
|
Rod about 3/8 inch in diameter (should be about one-half the inside
|
|||
|
|
diameter of the 4-inch long tube)

|||

|

|
|
Stove or hot plate

Knife
|

|
|
Measuring container
|
|||
|
|
|
|||
|
|
Preparation:
|
|||
|
|
1. Place 6 tablespoons of aluminum powder in a mixing bowl then add
|
|||
|
|
15 tablespoons of powdered sulfur.
|
|||
|
|
2. Mix the two powders gently with the spoon for a few minutes until
|
|||
|
|
no unmixed particles of sulfur are visible.
|
|||
|
|
3. In a separate pot add two teaspoons of laundry starch to about 6
|
|||
|
|
ounces of water and boil gently for a few minutes. Stir until the
|
|||
|
|
starch is dissolved and allow the solution to cool to room
|
|||
|
|
temperature.
|
|||
|
|
4. When cool, take about one-half of the starch solution and add it to
|
|||
|
|
the mixture of aluminum and sulfur powder.
|
|||
|
|
5. Mix with a spoon until the whole mass is a smooth, evenly mixed,
|
|||
|
|
putty-like paste.
|
|||
|
|
6. Fill the cylindrical tube with this paste. Place one end of this
|
|||
|
|
tube on a hard surface and tamp the paste with the 3/8 inch
|
|||
|
|
diameter rod to squeeze out the air bubbles and consolidate the
|
|||
|
|
paste.
|
|||
|
|
7. Push the paste out of the tube with the larger diameter rod, which
|
|||
|
|
just fits the tube, and pushes out a tube of paste. Cut the
|
|||
|
|
cylinder into 1 1/2 inch blocks.
|
|||
|
|
8. Dry these pieces at 90<39>F for at least 24 hours.
|
|||
|
|
9. Drill a small hole in one end of the pellets and fill it with
|
|||
|
|
gunpowder. In that put a fuse. Tape the fuse down.
|
|||
|
|
|
|||
|
|
Use with Thermite:
|
|||
|
|
|
|||
|
|
A cluster of three pellets should be used. Bury the pellets in the
|
|||
|
|
thermite. Light the fuse and the target will soon be melted.
