Understanding the characteristics and functions of inorganic chemical explosives is paramount in ensuring safe handling and proper utilization in explosive ordnance disposal operations.
Low Explosives vs. High Explosives
Low explosives and high explosives are two categories based on their rate of decomposition. Low explosives deflagrate, burning rapidly but not instantaneously, ideal for applications like propellants. High explosives, on the other hand, detonate rapidly, producing a supersonic shockwave for destructive force, commonly used in military ordnance.
An example of a low explosive is black powder, typically a mixture of potassium nitrate, charcoal, and sulfur. It burns rather than detonates, finding use in fireworks and early firearms. In contrast, a high explosive like TNT undergoes rapid decomposition, generating a high-pressure shockwave crucial for demolitions and military projectiles.
Understanding the distinction between low and high explosives is vital in explosive ordnance disposal operations. Proper identification ensures the appropriate safety measures are taken, considering the differing behaviors and risks associated with each type during handling and disposal procedures. Awareness of their characteristics aids EOD professionals in effective mitigation strategies.
Military Grade Explosives
Military grade explosives refer to high-quality, precisely manufactured explosive materials primarily designed for military applications.

Black Powder
Black Powder, a traditional form of explosive, consists of a mixture of sulfur, charcoal, and potassium nitrate. Historically used in firearms and mining, Black Powder is a low explosive, producing a subsonic deflagration rather than a supersonic detonation like high explosives. Its chemical composition allows for a controlled burn rate, making it ideal for applications where a slower release of energy is required. When ignited, Black Powder generates a large volume of gas, propelling projectiles or causing controlled explosions.
The components of Black Powder play distinct roles; sulfur acts as a fuel source, charcoal provides carbon for combustion, and potassium nitrate serves as an oxidizing agent. This combination results in a self-sustaining reaction that releases energy in the form of heat and gas. Despite its historical significance, Black Powder is less commonly used today due to its lower energy output compared to modern explosives. However, it remains valuable in certain applications where a less powerful explosive is needed.
Due to its stability and controllable nature, Black Powder finds use in fireworks, pyrotechnics, and antique firearm replicas. Its traditional composition and predictable behavior make it a suitable choice for activities where safety and precision are paramount. While overshadowed by more potent explosives in many military and industrial settings, Black Powder continues to hold a niche role in specific applications requiring a reliable and manageable explosive substance.
