Ammonium perchlorate Edit. Synonyms: Perchloric acid ammonium salt Description: Ammonium perchlorate is an oxidiser used in a large number of impressive colour compositions can be made with it, but their burn rate is often too low for use in star compositions.

Ammonium perchlorate (NH4ClO4) has been used as an energetics booster in rocket fuels, and it appears most perchlorate contamination is the result of discharge from rocket fuel manufacturing plants or from the demilitarization of weaponry (missiles). It is important to emphasize that ammonium perchlorate is not rocket fuel; it is an additive.

Ammonium Perchlorate xfine, 60130 micron, with dust Stock #C109B OX This is a mixture of finer granulations passing 60 microns. General purpose fireworks use. No ATFE required to purchase any of our ammonium perchlorate in less than full drum quantities.

Apr 18, 1972· Granular ammonium perchlorate having a particle size of 40 to 50 mesh is packed to a bulk density of from about to g/cc in a rocket motor casing restricted to maintain a chamber pressure in the range of from about 100 to about 2,000 psia and is used as the sole source of propellant gases for propelling a rocket.

Ammonium perchlorate. These corrosion data are mainly based on results of general corrosion laboratory tests, carried out with pure chemicals and water solutions nearly saturated with air (the corrosion rate can be quite different if the solution is free from oxygen).

Abstract. In this paper, ammonium perchlorate NH 4 ClO 4 (AP) was studied using synchrotron angledispersive Xray powder diffraction (XRPD) and Raman spectroscopy. A diamondanvil cell was used to compress AP up to 50 GPa at room temperature (RT). Density functional theory (DFT) calculations were performed to provide further insight and comparison to the experimental data.

1940's: Largescale production of perchlorate begins, expanding along with the growth of the postwar militaryindustrial complex. 1952: Perchlorate is found to impair normal thyroid function by interfering with iodine uptake by the thyroid gland (1). 1957: Study shows that perchlorate can pass through the placenta and can affect fetal animals more seriously than adults (2).

The most common use for ammonium perchlorate is in explosives and rocket propellant. Because it has a limited shelf life, the ammonium perchlorate used in the nation's rocket and missile supply must occasionally be replaced. As a result, large amounts of the compound are periodically disposed of .
