Melilite-type gallium oxides are potential intermediate temperature electrolytes for solid oxide fuel cells. Single crystals of [CaNd]2[Ga]2[Ga2O7]2 grown using an optical floating zone furnace have been investigated using transmission electron microscopy and powder and single-crystal X-ray diffraction. The anion array topologically conforms to a [(126.96.36.199)2, 188.8.131.52] network that contains distorted pentagonal tunnels. The distortion is necessary to achieve space filling and accommodate...[Show more]
