Explosive materials are substances that undergo rapid chemical reactions, producing gas and heat, which can result in an explosion. These materials are commonly used in various applications, including construction, mining, and military operations. Examples of explosive materials include dynamite, TNT, and ANFO (ammonium nitrate fuel oil). The behavior of explosive materials is influenced by their chemical composition and physical properties. They can be classified into two main categories: high explosives, which detonate and produce a shock wave, and low explosives, which deflagrate and burn more slowly. Proper handling and storage are essential to ensure safety when working with these materials.
