Abstract
Abstract: La3M4+Ga5O14 (M=Ti, Zr, Hf) compounds were crystallized using the micro-pulling down and Czochralski techniques. Both growth methods showed that these three crystals are peritectic compounds. The structure of La3TiGa5O14 (LTiG) crystal was refined using single-crystal X-ray diffraction data. LTiG was observed to be isostructural to Ca3Ga2Ge4O14 (P321 (No.150), Z=1) and the lattice parameters are a=8.223(1), c=5.109(1) Å. The Ti atoms were found to occupy octahedral (1a) and tetrahedral (3f) sites coordinated by six and four oxygen atoms, respectively.

Both growth methods showed that these three crystals are peritectic compounds. The structure of La3TiGa5O14 (LTiG) crystal was refined using single-crystal X-ray diffraction data. LTiG was observed to be isostructural to Ca3Ga2Ge4O14 (P321 (No.150), Z=1) and the lattice parameters are a=8.223(1), c=5.109(1) Å. The Ti atoms were found to occupy octahedral (1a) and tetrahedral (3f) sites coordinated by six and four oxygen atoms, respectively.</abstract><note type="content">Fig. 1: Projections of the La3MGa5O14 structure along the [010] direction (a), and normal to the [001] direction (b).</note><note type="content">Fig. 2: (a) La3TiGa5O14, (b) La3ZrGa5O14 and (c) La3HfGa5O14 crystals grown by the μ-PD method.</note><note type="content">Fig. 3: La3TiGa5O14 crystal grown by Cz technique using the residual melt after the first growth.</note><note type="content">Fig. 4: An ORTEP [17] drawing of part of the La3TiGa5O14 structure.
