The crystal structures of Sr 10 Ga 6 O 19 and Sr 3 Ga 2 O 6 have been characterized using X-ray di4raction techniques. In the case of Sr 10 Ga 6 O 19 , the structure was determined from a single crystal di4raction data set collected at room conditions and re5ned to a 5nal R index of 0.061 for 3471 o

the difference of their ionic valences causes defects in the structure or sometimes modification of the structure (7). A new phase in the system SrO-Al 2 O 3 -MgO, which was analyzed by EPMA as Sr 2 MgAl 22 O 36 , was recently found. It is The possibility to incorporate Mg in these structures conlo
In this paper we report the synthesis of a new phase in the La+Ti+Al+O system. A starting composition La 2 TiAlO 6.5 and synthesis conditions of 14003C under H 2 /Ar (5%/95%) resulted in a perovskite with a monoclinic (I 2/a; a ؍ 7.686, b ؍ 5.435, c ؍ 5.424 A s , ؍ 90.203) cell. Although it
