Single crystals with calcium gallium germanate (Ca 3 Ga 2 Ge 4 O 14 , CGG) structure such as langasite La 3 Ga 5 SiO 14 (LGS), its niobium (‘langanite’, La 3 Ga 5.5 Nb 0.5 O 14 , LGN) and tantalum (‘langataite’, La 3 Ga 5.5 Ta 0.5 O 14 , LGT) analogs as well as strontium niobium gallium silicate (Sr 3 NbGa 3 Si 2 O 14 , SNGS) and strontium tantalum gallium silicate (Sr 3 TaGa 3 Si 2 O 14 , STGS) were grown with high perfection by the Czochralski pulling technique. Specific electric conductivity, optical activity, and dielectric, piezoelectric, bulk and surface acoustic, elastic, and electro‐optic properties were measured.
