Jun 15, 2020· 1. Introduction. Ammonium perchlorate is a significant oxidizer for composite solid propellants (CSPs) (Yan et al., 2016; Zhang et al., 2014).The decomposition behavior of AP is crucial to the performance of propellants since it accounts for 60–90 wt% in CSPs (Zhang and Meng, 2016; Boldyrev, 2006).The peak temperature of high temperature decomposition (HTD) process (T HTD) is …

Ammonium perchlorate - Substance Information - ECHA

Summary of Perchlorate Uses and Sources Perchlorate (ClO 4-) is a soluble anion that forms solid salts with various cations, including ammonium, potassium, sodium, lithium, and magnesium. Once dissolved in water, perchlorate is very stable. It resists degradation in the subsurface and does not readily adsorb to mineral surfaces.

Ammonium perchlorate (AP) is produced by reaction between ammonia and perchloric acid.This process is the main outlet for the industrial production of perchloric acid. The salt also can be produced by salt metathesis reaction of ammonium salts with sodium perchlorate.This process exploits the relatively low solubility of NH 4 ClO 4, which is about 10% of that for sodium perchlorate.
