chemical formula: NH4ClO4
( powder )
The most frequently used oxidizer in most modern composite Rocket Propellant formulations. The Space Shuttle's solid
rocket boosters use a mixture of Ammonium Perchlorate and a form of Rubber as their rocket fuel. Ammonium Perchlorate is also used in most indoor, or
"low smoke" pyrotechnic mixtures. It is substantially more sensitive to ignition from friction or impact
(when mixed with other chemicals) than Potassium Perchlorate is.
