Structural and mechanical characteristics of complex oxide compounds Lu_2xGd_2-2xSiO₅:Ce (LGSO) crystals were studied at different cation ratio in the host. For this purpose, a series of LGSO crystals with Lu concentration 5-70 at.% has been grown by the Czochralski method. Anisotropy of mechanical properties for these materials has been studied. The obtained results can be useful at choice of optimal growth direction for crystals and at mechanical processing of scintillation elements.
