Abstract

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 Sr₃Nb_0.95Ga_3.083Si₂ 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.
