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 aluminium oxide is (briefly) molten and the produced iron is mostly liquid with part of it being in gaseous ...
Because thermate burns at higher temperatures than ordinary thermite, [1] it has military applications in cutting through tank armor or other hardened military vehicles or bunkers. As with thermite, thermate's ability to burn without an external supply of oxygen renders it useful for underwater incendiary devices.
When working with powdered magnesium, safety glasses with eye protection and UV filters (such as welders use) are employed because burning magnesium produces ultraviolet light that can permanently damage the retina of a human eye. [136] Magnesium is capable of reducing water and releasing highly flammable hydrogen gas: [137] Mg(s) + 2 H 2 O (l ...
When the fire involves burning metals like lithium, magnesium, titanium, [6] etc. (known as a class-D fire), it becomes even more important to consider the energy release. Because the metals react faster with water than with oxygen and thereby more energy is released, putting water on such a fire results in the fire getting hotter or even ...
As a result, neon burning occurs at lower temperatures than 16 O + 16 O. [9] During neon burning, oxygen and magnesium accumulate in the core of the star. At the onset of oxygen burning, oxygen in the stellar core is plentiful due to the helium-burning process ( 4 He(2α,γ) 12 C(α,γ) 16 O), carbon-burning process ( 12 C( 12 C,α) 20 Ne, 12 C ...
The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. [2] Practical applications include the sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous metals.
Nevertheless the burn rate of MTV, as is the case with many metallized pyrotechnic compositions is strongly dependent on the specific surface area of the metal fuel, that are particle morphology and dimensions. Generally magnesium powder having a high specific surface area will exhibit a higher burn rate than those having a smaller specific area.
