Spectral Transmittance of Single Crystal Ammonium Perchlorate and Deuterated Ammonium Perchlorate.

摘要

Ammonium perchlorate is widely used as an oxidizer in solid propellants. Little information about its spectral transmittance,is available. Such information would be helpful,for example,in estimating the effectiveness of radiation of a given wavelength in heating a crystal for decomposition. The spectral transmittance of large single crystals of ammonium perchlorate and deuterated ammonium perchlorate grown from aqueous solution has been measured in the ultraviolet,visible,near infrared,and infrared regions of the spectrum. The absorption edge of both the deuterated and undeuterated crystals lies in the ultraviolet regions near 200nanometers. There are strong absorption bands in the near infrared and infrared regions.
