  • This report describes methods and measurements of high-explosive products.
  • We present equation of state results from impulsively stimulated light scattering (ISLS) experiments conducted in diamond anvil cells on pure supercritical fluids, and supercritical fluid mixtures. We have made measurements on fluid H2O (water), CH2O (formaldehyde), and CH3OH (methanol). Sound speeds measured through ISLS have allowed us to refine existing potential models used in the EXP6 detonation product library [Fried, L. E., and Howard, W. M., J. Chem. Phys. 109 (17): 7338-7348 (1998).]. The refined models allow us to more accurately assess the chemical composition at the Chapman-Jouget (C-J) state of common explosives. We predict that water and formaldehyde aremore » present in appreciable quantities at the C-J state of HMX, RDX, and NM. Methanol is predicted to be present only in trace quantities at the C-J state. In the case of methanol, chemical decomposition and phase separation was observed at high temperatures. We are developing micro-FTIR and Raman techniques to determine the chemical composition of the phase separated detonation products.« less

  • Highly anisotropic particles of various thallium containing superconductors were grown. The Tl free precursor powders with the nominal compositions Ba{sub 1}Ca{sub 2}Cu{sub 3}Ag{sub 0.37}O{sub 6} and Ba{sub 2}Ca{sub 2}Cu{sub 3}Ag{sub 0.37}O{sub 7} were prepared using an aerosol flow reactor. These precursor powders were post-annealed in 0.1 atm oxygen at 700{degree}C for 4h to reduce the carbon present, and subsequently mixed with Tl{sub 2}O{sub 3} (typical composition of Tl{sub x}; x = 0.6 {minus} 1.0). The Tl-containing powders were heat-treated in semi-sealed gold tubes between 650--890{degree}C with various short and long heat-treatments. X-ray diffraction showed that the Tl{sub 1}Ba{sub 2}Ca{sub 1}Cu{submore » 2}O{sub 7} (referred to as Tl-1212) and Tl{sub 1}Ba{sub 2}Ca{sub 2}Cu{sub 3}O{sub 9} (Tl-1223) phases formed below 700{degree}C while Tl{sub 2}Ba{sub 2}Ca{sub 1}Cu{sub 2}O{sub 8} (Tl-2212) formed between 700--830{degree}C, and Tl{sub 2}Ba{sub 2}Ca{sub 2}Cu{sub 3}O{sub 10} (Tl-2223) formed above 830{degree}C. Scanning electron microscopy showed evidence for the presence of high aspect-ratio particles. These highly anisotropic particles may be of interest for the preparation of powder-in-tube and other powder-deposited conductors, for current leads, and for grain alignment studies.« less
