The ignition point has nothing to do with whether it is pure oxygen, but because the reaction in pure oxygen is more violent, once there is a local area to reach the ignition point of combustion, the heat released will make the temperature of other areas rise and it is easy to reach the ignition point, so it seems that it is easy to burn in pure oxygen, but the ignition point does not change.

The cooling rate in the quenching process of alloy products is one of the important factors affecting the alloy process, and rapid cooling can control the brittle carbide film at the grain boundary level. When the solution temperature of the alloy is higher than 1175, it is also easy to form carbide films at the grain boundaries. After long-term aging, the alloy shows a certain degree of aging hardening, which reduces the plasticity and high-temperature strength.

Magnesium metal can be burned in the air, and even in carbon dioxide, and some metals are also in danger of burning in the air after being made into powders**; There are also many metals that can be burned in pure oxygen, such as iron, aluminum, lithium, sodium, and so on; Only some extremely inactive metals, such as gold and platinum, do not burn even in pure oxygen.

Combustion is a violent chemical reaction, and accompanied by obvious heat and luminescence phenomenon, oxygen is a common accelerant, many substances that cannot be burned in the air, will also be ignited in pure oxygen.

Combustion in the air.

Magnesium is the most common metal that can ignite in the air, such as some electronic products in order to reduce weight, using very light magnesium aluminum alloys.

The reason why magnesium can ignite in the air is because magnesium has a very strong reducing ability, especially the binding ability with oxygen atoms is very strong, and even can "snatch" oxygen atoms from carbon dioxide, so metal magnesium can be burned in carbon dioxide to generate magnesium oxide (MGO) and carbon element, so when magnesium combustion fires, carbon dioxide fire extinguishers cannot be used to extinguish fires.

Metal powders. Many metals cannot be burned in the air under normal circumstances, and oxides will be generated on the surface when heated, such as iron, aluminum, etc., but after we make these metals into very fine powders, a large number of them will be burned and even occur when they float in the air, that is, dust**. There are many metals that can cause dust, such as iron powder, aluminum powder, zinc powder, etc.

For solid matter, the energy of the surface atoms is greater than the energy of the internal atoms, there is a physical quantity in physics called "surface energy", for powdery metals, the surface energy will become very large, which greatly reduces the conditions for metal combustion, so some metals will burn or even ** in the dust state.

Combustion in pure oxygen.

Since metals are reducible and oxygen is oxidizing, most metals are ignited in pure oxygen, for example, iron can be burned in pure oxygen, and then iron oxide (Fe2O3) is formed, and aluminum can also be burned in pure oxygen.

Non-combustible metal.

There are only a few extremely inactive metals that do not burn even in pure oxygen, such as gold and platinum; Even oxidized gold (AU2O3, commonly known as gold dew) will release oxygen to reduce elemental gold when it is under light or higher than 110, and it seems that real gold is not afraid of fire refining There is a certain reason.

For gold, it is also useless in the face of the more oxidizing fluorine, which can be ignited in fluorine gas (F2) to form gold trifluoride.
