X-ray topography study of LiB3O5 crystals grown from molybdate flux

The real defect structure of LiB3O5 crystal grown by a top seeded solution growth method has been observed using x-ray projection and reflective topography. Space mapping of such defects as growth sector boundaries, striation and dislocations have been produced by the topography analysis. The density of the dislocations is as low as <30 cm −2 .I t has b een shown that the dominant part of the dislocations detected is generated in the under-seed zone of the crystal.
