Methods for Studying Single-Crystal Aluminum-Oxide Fibers

The central avenues for studying the fine structure of single-crystal α-Al 2 O 3 fibers obtained by pulling from melt onto a seed (EFG) and with thinning of the feeder by laser radiation (LHPG) are presented. The crystallographic orientation of single-crystal α-Al 2 O 3 fibers was investigated using...

Zusammenfassung:The central avenues for studying the fine structure of single-crystal α-Al 2 O 3 fibers obtained by pulling from melt onto a seed (EFG) and with thinning of the feeder by laser radiation (LHPG) are presented. The crystallographic orientation of single-crystal α-Al 2 O 3 fibers was investigated using optical and scanning electron microscopes. It is suggested that x-ray diffraction topography be used to study the degree of perfection of single-crystal α-Al 2 O 3 fibers and to observe the boundaries of blocks and individual dislocations.
