Oxygen-balanced iron thermite 2Al + Fe 2 O 3 has theoretical maximum density of 4.175 g/cm 3 an adiabatic burn temperature of 3135 K or 2862 °C or 5183 °F (with phase transitions included, limited by iron, which boils at 3135 K), the aluminum oxide is (briefly) molten and the produced iron is mostly liquid with part of it being in gaseous ...
The composition by weight of Thermate-TH3 (in military use) is 68.7% thermite, 29.0% barium nitrate, 2.0% sulfur and 0.3% binder (such as polybutadiene acrylonitrile (PBAN)). As both thermite and thermate are notoriously difficult to ignite, initiating the reaction normally requires supervision and sometimes persistent effort.
[1] The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the detonation pressure.
The Siege and Destruction of Jerusalem by the Romans Under the Command of Titus, A.D. 70, by David Roberts (1850), shows the city burning. Early thermal weapons, which used heat or burning action to destroy or damage enemy personnel, fortifications or territories, were employed in warfare during the classical and medieval periods (approximately the 8th century BC until the mid-16th century AD).
The flame speeds are not the actual engine flame speeds, A 12:1 compression ratio gasoline engine at 1500 rpm would have a flame speed of about 16.5 m/s, and a similar hydrogen engine yields 48.3 m/s, but such engine flame speeds are also very dependent on stoichiometry [5]
Accroides resin , higher burning rate than shellac, burns well even with potassium perchlorate. Suitable for chrysanthemum stars. When metallic fuels are used, the metal particle size is important. A larger surface area to volume ratio leads to a faster reaction; this means that smaller particle sizes produce a faster-burning composition.

Designed to ignite vegetation, storage facilities, or fuel, these incendiary elements consist of hexagonal prisms made from a magnesium alloy known to the Russian GOST as ML-5, [26] [27] filled with a thermite mixture. [14] [28] Each element has a nominal length of 40 mm and a width of 25 mm and a burning time of at least 2 minutes. It is also ...
