Abstract
Abstract Iodine oxides are of interest as biocidal components in energetic application such as thermites due to their high energy release and biocidal agent delivery. In this study, various iodine oxides/iodic acids, including I 2 O 5 , HI 3 O 8 and HIO 3 , were employed as oxidizers in thermite systems. Their decomposition behaviors were studied using a home-made time resolved temperature-jump/time-of-flight mass spectrometer (T-Jump/TOFMS), which identified a single step decomposition for all oxides at high heating rates (∼10 5 K/s). In addition, both nano-aluminum (nAl, ∼80 nm) and nano-tantalum (nTa, 3 O 8 has the highest pressurization rate and peak pressure and shortest burn time, and since it also has an iodine content of ∼75% as high as I 2 O 5 on a per mass basis, this material may be a very promising candidate in biocidal application.
