采用Czochralski技术制备了新型Sr3TaGa3Si2O14（STGS）压电单晶。STGS的晶体结构与Ca3Ga2Ge4O14的晶体结构相同，具有三角形空间群P321， Z = 1。晶格参数为a = 8.293(2), c = 5.078(2) Å。1406个独特反射的最终R因子R = 0.047, Rw= 0.046。每个位点的阳离子分布都是有序的。报道了STGS的一些压电性能。
New piezoelectric Sr3TaGa3Si2O14(STGS) single crystals were grown using the Czochralski technique. The crystal structure of STGS is isostructural to that of Ca3Ga2Ge4O14, which has the trigonal space group P321 and Z = 1. The lattice parameters were a = 8.293(2) and c = 5.078(2) Å. The final R-factors were R = 0.047 and Rw= 0.046 for 1406 unique reflections. The distribution of each cation was found to be ordered in each site. Some piezoelectric properties of STGS are reported.
