AMMONIUM PERCHLORATE is a strong oxidizing agent. Decomposes at 130°C and explodes at 380°C [Mellor 2 Supp. 1:608 1956]. Explosions have occurred in propellant formulations containing ammonium perchlorate to which ferrocene has been added as a burning rate catalyst.

The invention provides a crushed particle size control method of fine ammonium perchlorate. An original intermittent feeding manner is replaced with a continuous feeding manner, and continuous feeding is performed through a feeding system, therefore, the materials in a grinding chamber are kept relatively constant, and the problems of material blocking caused by excess materials in the ...

The 5 parts potassium dichromate in the formula is best ballmilled with the 50 parts ammonium perchlorate to reduce the dichromate to fine powder while also maknig intimate contact with the AP. Avoid brass or bronze media when milling AP, due to the presence of copper which can make AP more sensitive. A clean jar and media is a must.

KClO3/Al- breaks tube like perchlorate flash, maybe a little more brisant, but not worth the extra sensitivity. According to Klapotke this should be much more powerful than Perchlorate flash, his balistic motor test showed this has 80% the power of Lead Azide. Ammonium Perchlorate/Mg- Just opens tube. Ammonium Perchlorate/Al- impossible to ignite.

AP. Upon opening the jar some hours later after milling, the AP has. been milled to a much finer powder, but is now almost completely stuck. to the insides of the jar. The layer is very hard, and is difficult. to remove. The inner surface of the jar is unvarnished porcelain, which is relatively rough.

. Create. . Ammonium perchlorate appears as a white, crystalline solid or powder. Classified as a division 1.1 explosive if powdered into particles smaller than 15 microns in diameter or if powdered into larger particles but thoroughly dried. Does not readily burn, but will burn if contaminated by combustible material.

In this research, hematite nanoparticles (α-Fe2O3 NPs) with spherical morphology were synthesized by high-energy ball-milling method for different milling times (40 and 60 h) at dry medium. The synthesized α-Fe2O3 NPs were characterized by X-ray diffraction and field-emission scanning electron microscope (FE-SEM) techniques. An average particle size (APS) of α-Fe2O3 NPs after 40 …
