X-ray topographic study of the perfection of flux-grown rare earth phosphates


Journal Article

X-ray topography has been used to study the perfection of crystals of TbPO4, DyPO4, HoPO4 and YbPO4 which were grown from Pb2P2O7 flux by slow cooling. The average dislocation density in optically clear specimens was typically 104 cm-2 and in some thin plates there were quite large areas which were dislocation-free. Evidence that appreciable plastic deformation had occured after growth was found in all specimens. The quality of the crystals is compared with that of crystals of rare earth vanadates, RVO4, which were grown under similar conditions. © 1975.
