Conventional Czochralski growth of large Li2MoO4 single crystals

Lithium molybdate single crystals up to one kilogram have been grown by a conventional Czochralski process. The growth configuration (geometry, coil, crucible, insulation casing) was optimized numerical simulation of heat and mass transfer. Dislocations are shown belong the basal glide system. Their density (≤104 cm−2) luminescence properties indicate crystal quality similar that previously reported technique. Numerical thermo-elastic stresses suggest crack observed in these is rather due mechanical accident than internal during growth.
