Title: Heavy ion irradiations on synthetic hollandite-type materials: Ba{sub 1.0}Cs{sub 0.3}A{sub 2.3}Ti{sub 5.7}O{sub 16} (A=Cr, Fe, Al)

Abstract

The hollandite supergroup of minerals has received considerable attention as a nuclear waste form for immobilization of Cs. The radiation stability of synthetic hollandite-type compounds described generally as Ba{sub 1.0}Cs{sub 0.3}A{sub 2.3}Ti{sub 5.7}O{sub 16} (A=Cr, Fe, Al) were evaluated by heavy ion (Kr) irradiations on polycrystalline single phase materials and multiphase materials incorporating the hollandite phases. Ion irradiation damage effects on these samples were examined using grazing incidence X-ray diffraction (GIXRD) and transmission electron microscopy (TEM). Single phase compounds possess tetragonal structure with space group I4/m. GIXRD and TEM observations revealed that 600 keV Kr irradiation-induced amorphization on single phase hollandites compounds occurred at a fluence between 2.5×10{sup 14} Kr/cm{sup 2} and 5×10{sup 14} Kr/cm{sup 2}. The critical amorphization fluence of single phase hollandite compounds obtained by in situ 1 MeV Kr ion irradiation was around 3.25×10{sup 14} Kr/cm{sup 2}. The hollandite phase exhibited similar amorphization susceptibility under Kr ion irradiation when incorporated into a multiphase system. - Graphical abstract: 600 keV Kr irradiation-induced amorphization on single phase hollandites compounds occurred at a fluence between 2.5×10{sup 14} Kr/cm{sup 2} and 5×10{sup 14} Kr/cm{sup 2}.

  • Criteria for the safe immobilization of /sup 137/Cs in synthetic hollandite-type phases are reviewed with respect to chemical, crystallographic, and physical stability, including possible radiation damage, following ..beta.. decay of /sup 137/Cs/sup +1/ ..-->.. ..beta../sup -/ + /sup 137/Ba/sup 2 +/. Whereas synthetic preparations so far possess properties which offer some optimism that a relatively stable waste product is possible following changes in charge and ionic radius of the radioactive ions, this is by no means established.
  • Bi[sub 1.7]V[sub 8]O[sub 16] was synthesized by high temperature solid state reaction between Bi[sub 2]O[sub 3], V[sub 2]O[sub 5], and V[sub 2]O[sub 3]. The compound crystallizes with tetragonal symmetry, space group I4/m. The structure refinement using single crystal data confirms that the compound belongs to the hollandite family. It is the first hollandite-type compound containing bismuth in the large tunnels of the V[sub 8]O[sub 16] framework. The bismuth atom forms a very flat BiO[sub 4] square pyramid with the skeleton oxygen systems. Bi[sub 1.7]V[sub 8]O[sub 16] is oxidized to BiVO[sub 4] and V[sub 2]O[sub 5] at 400[degrees]C in air, asmore » evidenced by TGA and DSC.« less
  • Single crystals of NdMo{sub 6}O{sub 12} were prepared by fused-salt electrolysis at 960 C from a melt of Rb{sub 2}MoO{sub 4}, MoO{sub 3}, and Nd{sub 2}O{sub 3} having the molar ratio 8.4:5:1. The compound crystallizes in the tetragonal space group I4/m with a = 9.8988(2) {angstrom}, c = 8.6434(5) {angstrom}, V = 846.93(5) {angstrom}{sup 3}, and Z = 4. The structure of NdMo{sub 6}O{sub 12} has been determined from single-crystal X-ray diffraction data and refined to reliability factors of R(F{sub o}) = 0.0409 and R{sub w}(F{sub o}{sup 2}) = 0.0612 for all the reflections (1282). NdMo{sub 6}O{sub 12} adopts amore » hollandite-related structure with a tripled c-axis. Within the double chains of edge-sharing MoO{sub 6} octahedra, the Mo atoms form infinite chains of Mo{sub 3} triangular clusters. Another dominant feature of the structure is the ordering of the Nd{sup 3+} cations within the channels delimited by the Mo-O double strings. NdMo{sub 6}O{sub 12} shows semiconducting behavior along the chains with an activation energy of 0.3 eV and a room-temperature resistivity of 0.49 {Omega}{center_dot}cm. The magnetic susceptibility data indicate paramagnetic behavior due to the Nd{sup 3+} moment at high temperature.« less
  • A hollandite-type manganese dioxide (HolMO), without foreign metal cations (K[sup +], NH[sup +][sub 4], Na[sup +]) in the (2 [times] 2) tunnel, was prepared directly by reacting LiMnO[sub 4] with Mn(NO[sub 3])[sub 2] in an H[sub 2]SO[sub 4] acidic solution. The HolMO belonged to a body-centered tetragonal system (space group 14.m) and could be expressed by the formula H[sub 4x]Mn[sub 8[minus]x]O[sub 16][center dot]yH[sub 2]O. A preliminary electrochemical study suggested that the HolMO is promising as the cathode for a lithium rechargeable battery.
