    Abstract

    We present evidence for finite and/or imperfect low-angle grain boundaries and associated long-range stress fields, formed during the hydrothermal growth of berlinite (alpha-AlPO4) crystals on multiple-seed-plate arrays. These defective boundaries originate at angularly misaligned junctions between adjacent seed plates as a result of the failure of some component sets of dislocations to propagate epitaxially into the new growth. Lacking a full complement of dislocations, the newly grown boundary may be imperfect and generate long-range stresses, leading to fracture and/or plastic flow. (C) 1998 Elsevier Science B.V.
