Current trends in the study of the fine structure of ?-Al 2 O 3 single crystal fibers obtained by pulling from the melt onto a seed (EFG) and by thinning a feeder using laser heating (LHPG) are presented. ). Studies of the crystallographic orientation of ?-Al 2 O 3 single crystal fibers have been carried out on an optical and scanning electron microscope. The use of X-ray diffraction topography for studying the perfection of the obtained single-crystal ?-Al 2 O 3 fibers and observing the boundaries of blocks and single dislocations is proposed.
