The stoichiometric composition (Sr3NbGa3Si2O14) was found to melt incongruently. Hence, the composition of the starting melt for Czochralski growth was chosen from the differential thermal analysis (DTA) results. We found that Sr3Nb0.95Ga3.083Si2 O14 (SNGS) was the proper composition to grow. This resulted in SNGS single crystals having a Ca3Ga2Ge4O14 (CGG) structure (point group 32, space group P321), grown by the conventional Czochralski method.
