Low-explosives are a type of explosive material that burn rapidly but do not produce a shock wave. They are commonly used in applications such as fireworks, blasting in mining, and propellant for firearms. These explosives generate gas and heat, which can create pressure but do not result in a violent explosion like high-explosives. The most common example of low-explosives is black powder, which consists of a mixture of charcoal, sulfur, and potassium nitrate. Other examples include smokeless powder, used in ammunition, and various types of pyrotechnics. Low-explosives are generally safer to handle than high-explosives, making them suitable for controlled applications.
