Abstract
The stoichiometric composition (Sr3NbGa3Si2O14) was found to melt incongrue ntly. Hence, the composition of the starting melt for Czochralski growth wa s chosen from the differential thermal analysis (DTA) results. We found tha t Sr3Nb0.95Ga3.083Si2O14 (SNGS) was the proper composition to grow. This re sulted in SNGS single crystals having a Ca3Ga2Ge4O14 (CGG) structure (point group 32, space group P321), grown by the conventional Czochralski method. (C) 2001 Elsevier Science B.V.
