Heat of phase transition of ammonium perchlorate from orthorhombic to cubic modification is 11.3 kJ/mol [6]. The unit cell of the orthorhombic modification contains four molecules. The unit cell parameters are: a = 0.9202, b = 0.5816 and c = 0.7449 nm. Four oxygen atoms form a tetrahedron around the chlorine atom.
These propellants are harder to ignite than black powder or sugar based propellants and require a longer burning, more intense igniter. John Wickman is his great book How to Make Amateur Rockets gives these two formulas for composite propellant: Ammonium perchlorate. Aluminum. R45M Binder.
Perchlorate is an anion that is easily dissociated from salts such as ammonium perchlorate or sodium perchlorate. In 1997, perchlorate was detected in the drinking-water supplies in the southern regions of California and Nevada at levels of 4 to 16 µg/L (Lamm and Doemland 1999; Soldin, Braverman, and Lamm 2001).
Gender: Male. Posted 12 April 2023 - 04:54 AM. Ammonium perchlorate forms a more shock sensitive coordination compound with copper metal, just like ammonium nitrate does, and its thermal decomposition is also catalyzed by zinc dust and probably by some other metals. So it's best to make sure that the balls and the inner …
Rocket propellants that contain ammonium perchlorate (AP) often have a violent response during slow heating. Two laboratory tests have been developed to determine the reaction violence of these materials. The first test was the Combustion Rate Analysis of a Slowly Heated Propellant (CRASH-P) test, which used dynamic pressure …
motors. Ammonium perchlorate replaced potassium perchlorate as an oxidizer in the late 1940's, and binders were developed. Discoveries important in the evolution of large solid-propellant motors appear to have resulted from innovators' education and skills, an exposure to contemporary problems, an awareness of theory but a
List of materials that have been micronized and/or processed in Jet Pulverizer Micron-Master® mills through our advanced micronizing services. ... Ammonium Perchlorate. Ammonium Phosphate. Ammonium Sulfate. Anthraquinone. Antibiotic. Anti-Microbial Powder. Antimony Pentoxide. Antimony Sulfide. Antimony Trisulfide. Ascorbic Acid.
Ammonium Perchlorate (CAS no. ), 99.8% purity, was obtained from Aldrich Chemical Company, Inc. (Milwaukee, Wisconsin, lot 03907LF) and used at both sites. Test formulations of AP in reverse osmosis membrane processed deionized water (R.O. deionized water) were prepared at least weekly, stored refrigerated, and dosage …
Ammonium perchlorate, and acetone peroxide. The latter is much more sensitive, and has no use in actual pyrotechnics. It's more of a high explosive. Thanks for your advice Mumbles, Ammonium perchlorate is what I had in mind. Acetone peroxide is out of my interest as it is very dangerous. I will use coffee grinder.
Abstract A flake aluminum powder (f-Al) is prepared by a bi-directional rotation mill method using a spherical aluminum powder (s-Al) as a raw material. Then, these two kinds of aluminum powders are used to prepare ammonium perchlorate-based composite modified double-base (AP-based CMDB) propellants. The properties of two …
Ammonium perchlorate is an explosive agent used as a component of fireworks, flash powders, explosives, smokeless jet, and rocket propellants. It is also used in oxidizing, engraving, or etching compounds, and as a reagent in analytical chemistry. Historically, perchlorate salts have been used therapeutically to treat hyperthyroid disorders ...

Ammonium Perchlorate. Calibre Chemicals has been supplying Ammonium Perchlorate in aerospace, national defense programs and commercial applications. Ammonium Perchlorate is the leading oxidizing agent for solid propellant rockets, booster motors and missiles that are used in space exploration, commercial satellite transportation and …
Ammonium perchlorate was continuously ground in a jet mill with helium gas and with nitrogen gas for comparison. The highest grinding efficiency and submicron-sized fractions were developed when heated helium was used. Continuous mixing of the ground oxidizer, with the other propellant ingredients dispersed in an inert gas, is proposed in a specially …
The regimes of non-explosive mechanical treatment of ammonium perchlorate (AP) in high-energy intensity planetary ball mill are found. The changes in the structure and reactivity of AP as a result of mechanical processing were studied by methods of synchronous thermal analysis with registration of mass spectra, x-ray diffraction, …
At the same time, the catalytic performances of the Al-1 and as-prepared Al powder on the thermal decomposition of ammonium perchlorate (AP) are studied through thermogravimetric and differential scanning calorimetry analysis. The results revealed that compared with pure AP, the exothermic peak temperature of AP/Al-1, …
