摘要：

LiFePO4 single crystals were grown using optical floating zone technique. High quality crystals sized up to phi 5 x 70mm can be obtained by applying a growth rate of 2 followed by 4mm/h in an argon flow atmosphere. The single crystals exhibit blackish green color after cleaving from the as-grown ingot. DTA/TG and high temperature optical microscope measurements indicate that the compound melts incongruently. The study of XRD shows the orthorhombic structure of the crystals. (c) 2005 Elsevier B.V. All rights reserved.
