Ammonium perchlorate is a chemical compound with the formula N H₄Cl O₄. It is the salt of perchloric acid. Like other perchlorates, it is a powerful oxidizer.

This salt is used as an explosive in mines, due to the low temperature elevation that follows its decomposition.

It is produced by reaction between ammonia and perchloric acid, or by double decomposition between an ammonia salt and sodium perchlorate.

It crystallises in colorless rhomboedres with a relative density of 1,95. It is the least soluble of all ammonia salts with 20 g in 100g water at 0°C. It decomposes before fusion.
