Preparation and characterization of galo-titanogalate-type K_xGa₈Ga_8+xSn_16-xO₅₆

Abstract

Newly galo-titanogalate-type KxGa8Ga8+xSn16-xO56 (KGGSO; x~2) were prepared by solid state reaction method and flux slow cooling method. Solid solution region of KGGSO was 1.2<x<1.5. The lattice parameter variation of 1.3<x<1.5 corresponded to the ratio of Ga and Sn in octahedral site. Aggregate of needle-like KGGSO single crystal was also obtained by the following flux slow coolingmethod.
