Ion-Exchange Reaction Of A-Site In A2Ta2O6 Pyrochlore Crystal Structure

Abstract: Na + or K + ion rechargeable battery is started to garner attention recently in Place of Li+ ion cell. It is important that A+ site ion can move in and out the positive-electrode materials. When K 2 Ta 2 O 6 powder had a pyrochlore structure was only dipped into NaOH aqueous solution at room temperature, Na 2 Ta 2 O 6 was obtained. K 2 Ta 2 O 6 was fabricated from a tantalum sheet by a hydrothermal synthesize with KOH aqueous solution. When Na 2 Ta 2 O 6 was dipped into KOH aqueous solution, K 2 Ta 2 O 6 was o… Show more

“…For FeSbO 4 , we analyzed its first (oxygen) and third (metallic) shells. Such an oxide possesses a tetragonal unit cell belonging to the P4 2 /mnm space group (D 4h 14 or Nº 136). The Sb 5+ ions locate at 2a Wyckoff sites, half shared with Fe 3+ cations.…”
