摘要：

A(3)NbGa(3)Si(2)O(14) (A=Sr, Ca) compounds were grown using the Czochralski method after preparing by solid-state reaction. X-ray structure analysis of grown Sr(3)NbGa(3)Si(2)O(14) (SNGS) and Ca(3)NbGa(3)Si(2)O(14) (CNGS) single crystals showed that they were isostructural to that of Ca(3)Ga(2)Ge(4)O(14), which had space group P321. The lattice constants of SNGS and CNGS were calculated to be a=8.282, 8.087 and c=5.073, 4.980 Angstrom, respectively. The final R and R(w). values for the refinement were 0.0353 and 0.0354, respectively. Piezoelectric properties of these crystals were measured. (C) 2002 Elsevier Science B.V. All rights reserved.
