Gunpowder is an explosive material often used to make bullet barrels for handguns. The main ingredient of this mixture is the salt of potassium sodium.
Similar to other explosives, the shelf life of gunpowder is a matter of concern. So, how long does gunpowder last? What factors affect its lifespan?
In this article, we give full explanations to answer the above questions.
Let’s explore together!
How Long Does Gunpowder Last?
In the right conditions, gunpowder is likely to last indefinitely.
It is also why you often hear news of exploding war cannons hundreds of years ago. However, under less ideal conditions, its lifespan will also change.
The hydrolysis and exchange reactions will occur slowly when the chemical components inside are exposed to air or water for too long. The performance of this mixture will degrade significantly over time.
The first invention of gunpowder was from black powder, a mixture of potassium nitrate, coal, and sulfur in a ratio of 15:3:2.
In some places, one can replace potassium nitrate with sodium nitrate. However, this conductor quickly absorbs moisture and has much less stability.
In addition, people also take advantage of charcoal carbon to activate the combustion conductor in gunpowder.
The mixture in the cartridges is usually an amorphous solid. This texture makes it easier to create uniformity between compounds.
The traditional powder is not a single substance. But, it is a mixture of potassium nitrate, sulfur, and charcoal.
With modern technology, military institutes in many countries have produced “smokeless gunpowder.” This upgraded version comes with the absolute correct component ratio with a longer lifespan.
Some Factors Related To Gunpowder Life
Gun powder forms based on chemical topologies. Depending on the manufacturer, they all have their balanced formulas.
The conversion rate between substances is still not too big of a difference. Its lifespan is also determined based on several factors as follows:
Nitrocellulose acts as a catalyst for the active base and detonation of gunpowder.
It is distilled in a specialized medium through a blend of cellulose, nitrate, and sulfuric acid. Here, the impact factors such as temperature, pressure, and oxygen absorption will create Nitrocellulose.
In gunpowder, there is always excess Nitrocellulose in the single base and nitroglycerin in the double bass.
When exposed to air or high temperature, nitrogen and air from chemical radicals turn into acid radicals and destroy volatiles to create explosions.
During the export process, some other chemicals will avoid the deterioration of gun powder over time. However, this process also does not last long if the chemical breakdown happens too quickly.
When the fixing layer becomes weak, Nitrocellulose is easy to crack. It can destroy the last barrier in the gunpowder system, and the resulting gunpowder explodes.
If the powder is kept above the right temperature, the compound has a very long shelf life. Several articles have proven this point through the IIRC and naval tests.
NATO also researched 7.62 cartridges. They put it in an accelerated aging environment for spectral testing.
The ultimate conclusion is that the powder can last for hundreds of years under ideal humidity, temperature, and pressure conditions.
The barrels left after the war buried underground are the most compelling evidence for this result. They are more than ten years old or even hundreds of years old and still tend to remain if they are not available to external forces.
Stability and Storage
Ammo life and gunpowder life directly affect each other. As mentioned, Nitrocellulose is the primary raw material for maintaining stability.
Traditional gunpowder is from sodium nitrate, sulfur, and coal. However, the bonds between these derivatives can change under attack.
Once out of balance, the gunpowder becomes brittle and easier to inactivate. Therefore, large explosions often occur at gun barrels. Preservation for 20 to 40 years is possible if it is stored correctly and with little exposure to air.
A dry and cold environment is ideal for protecting gun powder storage.
In an enclosed space, it is necessary to thoroughly eliminate excess heat sources and limit all smoke or even sunlight sources.
It would help if you separated electronic devices or sparks from the power plug.
In the corners of the room, do not let water drip and accumulate grease, which can cause fire and explosion.
Tips For Storage & Destruction
Smokeless powder is a combustible material that harnesses thrust to deploy the barrel of a gun. It has three primary forms: small cylinders, small spheres, and thin circular plates.
Both traditional and smokeless gun powder is incredibly flammable. Here are some preservation methods that you may consider:
- Store them in a relaxed environment: Ensure ventilation and dryness
- Do not smoke in areas where gunpowder is stored.
- Do not transport mixed gunpowder without permission.
- Use signs to remind people
- Take precautions in the event of an emergency.
- Do not store the gunpowder in environments with solvents, floating gasses, and substances that can be combined.
- Experts recommend equipping cabinets made of heat-resistant materials.
Handling expired packs of gunpowder is not too complicated. One of the most straightforward solutions is cremation.
You must choose an area far from the population to ensure everyone’s safety. In addition, the performer also needs to learn techniques to avoid danger.
You can follow to step by step guide below:
- Place a long piece of paper where it needs to be burned
- Ensure the appropriate distance, so the operator has time to move to a safe place.
- Light a match to start the cycle.
- Clean up after the destruction
