Fireworks and Explosives Research Proposal Example | Topics and Well Written Essays - 1500 words

Fireworks and Explosives - Research Proposal Example As per the advanced analysis in of fireworks, it reveals that â€Å"potassium nitrate†, primarily the main chemical ingredient in gunpowder, is still an imperative element utilized in quite a lot of current explosives. (Michael S. Russell) An â€Å"explosion† is a chain of chemical reactions induced by fumed energetically unstable explosive materials that generate a rapid and aggressive oxidation reaction resulted in the production of the huge mass of hot gases and heat. Due to the mass force of gas and heat, it expands rapidly and forms a blast, further forming shock wave giving the blast its destructive power. (Gail Kay Haines) The â€Å"explosive train,† also termed as an initiation sequence or â€Å"firing train† is the series of charges that progress from moderately small levels of energy to instigate the absolute volatile material/main charge. There are two types of explosive trains Explosive materials comprise of any one of a chemically unadulterated compound like â€Å"nitroglycerin† or a mixture of an oxidizer and a fuel such as â€Å"black powder, flash powder, Sprengel explosives, ANFO, Panclastites† etc. For the understanding of explosive materials based on mixtures of fuel and oxidizers following equation can be useful: Diverse explosives utilize, unlike chemical reactions. The most primitive known explosive was gunpowder. Gunpowder or black powder is considered a grand historical significance in chemistry. The principal application of gunpowder is as a â€Å"propellant.† Gunpowder was invented by Chinese alchemists during the 9th century. (Appleton) The gunpowder was prepared by assimilating rudimentary sulfur, charcoal, and potassium nitrate. The â€Å"Potassium nitrate, sulfur in addition to carbon† retort collectively to produce nitrogen & carbon dioxide gases along with potassium sulfide.  Ã‚
