Crystallograhic textures of phases in eutectics Al 2 O 3 + ZrO 2 ( Y 2 O 3 ) were investigated by means of X-ray diffraction. In all studied eutectic polycrystalls (grown from the melt by EFG technique) apreferred orientation [0001] of Al 2 O 3 along the growth direction in all the samples was revealed forboth initial orientations of Al 2 O 3 seeding crystal: and . For a cubic ZrO 2 there weretwo types of a preferred orientations: sharp ones, close to with a 6-fold symmetry and morespread . Such a 6-fold symmetry for a cubic phase appears in eutectic due to a joint crystallization.
