Vacuum Sublimation of Ammonium Perchlorate.
Abstract
Time-of-flight measurements have been made on the flux of molecules from the surface of ammonium salts vaporizing into vacuum. As expected with ammonium halides and ammonium bi-sulfate the TOF distributions correspond to equimolar fluxes of ammonia and the corresponding acid. In the case of ammonium perchlorate the vapor subliming from a single crystal comprised ammonia and perchloric acid. When the source was compressed powder, the vapor was a mixture of lower molecular weight species. This result seems best explained in terms of subsurface decomposition. (Author)
