Abstract

Fuel-oxidizer mixtures based on potassium chlorate or sodium chlorate are well known. These mixtures have interesting properties of deflagration and are often used in propellants. Drastic reactivity of alkaline chlorates with ammonium salts due to the formation of ammonium chlorate NH₄ClO₃, a very unstable salt, is famous. By analogy, we tested the reactivity of different molecules containing nitrogen atoms, and we found an efficient fuel-oxidizer composed of potassium chlorate and thiocarbamide. Impressive bengal lights of various colors can easily be achieved using this basic composition.

  Graphite exfoliation is a well-known process in carbon chemistry. An intercalation compound is first synthesized using reactants with strong redox properties. The intercalated graphite is then heated and the exfoliation occurs: a graphite vermicular ...
