ShinSynopsis: The determined structure of lithium barium silicate, Li2BaSiO4, consists of two types of tetrahedra, viz. (SiO4)4- and (LiO4)7-, and Ba2+ atoms located at the centers of open spaces formed by the tetrahedra. These tetrahedra share edges to form (Li6SiO13)5- units. These basic units are connected by sharing corners (O atoms) parallel to [001] and through sharing (SiO4)4- tetrahedra in (001). Formula: Li2BaSiO4 Online 7 March 2009 |
