“…Iodine (V) oxides (I2O5, HI3O8, and HIO3) promise to be effective oxidizers in energetic materials for various applications [1][2][3]. This potential is largely due to their ability to increase the energy density and pressure impulse in multi-component energetic composites, as well as their ability to produce gaseous iodine (I2) and corrosive hydrogen iodide (HI) during decomposition, which exhibit biocidal behavior towards biological agents such as anthrax [4][5][6][7].…”

Physiochemical Characterization of Iodine (V) Oxide Part II: Morphology and Crystal Structure of Particulate Films

Abstract:In this study, the production of particulate films of iodine (V) oxides is investigated. The influence that sonication and solvation of suspended particles in various alcohol/ketone/ester solvents have on the physical structure of spin or drop cast films is examined in detail with electron microscopy, powder x-ray diffraction, and UV-visible absorption spectroscopy. Results indicate that sonicating iodine oxides in alcohol mixtures containing trace amounts of water decreases deposited particle sizes and produces a more uniform film morphology. UV-visible spectra of the pre-cast suspensions reveal that for some solvents, the iodine oxide oxidizes the solvent, producing I2 and lowering the pH of the suspension. Characterizing the crystals within the cast films reveal their composition to be primarily HI3O8, their orientations to exhibit a preferential orientation, and their growth to be primarily along the ac-plane of the crystal, enhanced at higher spin rates. Spin-coating at lower spin rates produces laminate-like particulate films versus higher density, one-piece films of stacked particles produced by drop casting. The particle morphology in these films consists of a combination of rods, plates, cubes, and rhombohedra structure.

“…In addition, we find that Immm-ZrN 10 and Immm-TiN 10 can also be metastable structures (dynamically and mechanically stable) at ambient pressure. The gravimetric energy density for Immm-TiN 10 is 5.2 kJ/g at ambient conditions (298 K, 0GPa), higher than that for the well-known explosive material TNT (4.3 kJ/g) and mildly lower than another powerful explosive HMX (5.7 kJ/g) [43] which are higher than TNT (7.2-8.0 kJ/cm 3 ), RDX (10.1 kJ/cm 3 ) and PETN (10.6 kJ/cm 3 ) [44,45]. The elastic moduli of all the Hf-N compounds are calculated according to the elastic constants tensors and theoretical hardnesses can be further predicted based on the Chen-Niu's empirical correlation [46] as listed in Table II.…”
