Abstract
Alkali-earth ion (Sr, Ba) substituted La3Ga5SiO14, and La(3)M(0.5)G(5.5)O(1 4) (M=Nb5+,Ta5+) compounds were synthesized by solid state reaction. Sr-sub stituted La3Ta0.5Ga5.5O14 (Sr-LTG) single crystals were grown by the micro- pulling down and Czochralski techniques. The cation distribution in Sr-LTG has been determined by X-ray structure analysis. Some piezoelectric propert ies of Sr-LTG crystal are reported and compared with those of pure La3Ta0.5 Ga5.5O14.
