  • 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 phasemore » 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}. The hollandite phase exhibited similar amorphization susceptibility under Kr ion irradiation when incorporated into a multiphase system. This is also the first time that the critical amorphization fluence of single phase hollandite compounds were determined at a fluence of around 3.25×10{sup 14} Kr/cm{sup 2} by in situ 1 MeV Kr ion irradiation.

  • Synthetic hollandite compounds of composition Ba/sub x/M(IV)/sub 4-2x/N(III)/sub 2x/O/sub 8/ (M=Ti, Ge, Ru, Zr, Sn; N=Al, Sc, Cr, Ga, Ru, In) and Sr/sub x/M(IV)/sub 4-2x/N(III)/sub 2x/O/sub 8/ (M=Ti, Ge, Ru; N=Al, Cr, Ga) and (A, Ba)/sub x/Ti/sub y/Al/sub z/O/sub 8/ with A=Rb, Cs, Ca, Sr have been studied by electron and X-ray diffraction and high resolution electron microscopy. They have been found to be stable only within certain ranges of x, depending on the M and N ions. The lower value of x is never less than 0.56, the upper x level is about 0.73. Higher x are correlated withmore » larger radii of M and N. The variation in x gives rise to an incommensurate occupation by the A ions in the tunnels. Correlation among tunnel sequences varies widely, also depending on the nature of the M and N ions. The lower and upper x, the cell dimensions, the correlation between the tunnels and the stability in water at 300/sup 0/C of the existing hollandites are given.« less

  • A series of barium-rich hollandite samples, of nominal stoichiometry Ba{sub x}Fe{sub 2x}Ti{sub 8-2x}O{sub 16}, with x=0.8-1.5 have been studied using scanning electron microscopy and synchrotron powder diffraction in order to establish the influence of Ba content on the phases formed. Samples with x between 1.1 and 1.3 were found to be single phase, samples with x<1.1 contained rutile as a secondary phase, and samples with x>1.3 contained (Ba, Fe) titanates as secondary phases. From synchrotron X-ray diffraction patterns, at room temperature, a transformation from the tetragonal (I4/m) to the monoclinic (I2/m) structure was observed between x=1.1 and 1.2. The monoclinicmore » angle, {beta} increases rapidly from 90.48(2) to 91.06(6) deg. as x increased from 1.2 to 1.4.« less
  • A wide range of barium titanate hollandites of the form Ba{sub x}{sup 2+}M{sub x}{sup 2+}Ti{sub 8-x}{sup 4+}O{sub 16} (M=Zn, Co, Mg, Fe and Mn) and Ba{sub x}{sup 2+}M{sub 2x}{sup 3+}Ti{sub 8-2x}{sup 4+}O{sub 16} (M=Fe) with nominal x ranging from 1.0 to 1.4 have been synthesized and examined to investigate the solid solution range and the nature of the ordering of the Ba ions. Electron diffraction studies confirm that the barium titanate hollandites are composite modulated single phase solid solutions made up of mutually incommensurable (along b) framework and Ba ion sub-structures. The overall superspace group symmetry was found to bemore » I'2/m(0,x2,0)1. The symbol I' here refers to the superspace centering operation {l_brace}x{sub 1}+12,x{sub 2}+12,x{sub 3}+12,x{sub 4}+12{r_brace} (see below). Both the framework and the Ba sub-structures have the same I2/m average structure space group symmetry. The solid solution ranges for the hollandites were calculated from the positions of well-defined superlattice peaks in X-ray diffraction patterns. The effect of cooling rate on Ba ion ordering is also examined.« less
