Abstract:Single crystals of CsGa7O11, RbGa7O11, and RbGa4In5O14 were grown from alkali halide melts and their structures were characterized by single crystal and powder X‐ray diffraction. CsGa7O11 and RbGa7O11 adopt the same structure type, reminiscent of the hollandite structure type, as it contains nearly rectangular channels made up of two dimers of edge‐sharing GaO6 octahedra, and two corner‐sharing octahedron/tetrahedron pairs. The structure of RbGa4In5O14 is more complex and is comprised of indium octahedra, gall… Show more
“…A set of Non-Rad simulant TCCR samples from Crystalline Silicotitanate columns (CST), containing less than 5 ppm Na were analyzed at a 200x and 100x dilution utilizing the described method [4] . In addition, Table 3 shows a set of 16 samples from a CsGa7O11 leaching study that were analyzed for total Cs and compared to ICP-MS [5] . A set of various matrix SPK samples were also prepared and analyzed (Table 3) with a spike recovery within 10% of the expected value, further demonstrating method accuracy and precision.…”

Single crystals of two new germanates, [(Rb6F)(Rb4F)][Ge14O32] and [(Rb6F)(Rb3.1Co0.9F0.96)][Co3.8Ge10.2O30F2], were synthesized via high temperature RbCl/RbF flux growth. Both compounds crystallize in the cubic space group F4 ̅3m and possess the...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
