Abstract :
K3Li2-xNb5+xO15+2x single-crystal fibers have been grown using the LHPG technique. Ceramic source rods of K3.00Li1.70Nb5.30O15.6 (KLN53), K3.00Li1.85Nb5.15O1.53 (K-LN51.5) and K3Li2Nb5O15 (KLN50) were adapted to grow the fibers with the same composition. Growth of KLN53 fibers was easier than that of KLN51.5 and KLN50 fibers. An orientation of <110> was preferable. A pulling rate of 98.0 mm/h was realized for the <110> oriented KLN53 single-crystal fiber. The <110> and <100> oriented KLN53 fibers were rectangular in shape, while the <001> oriented fiber was cylindrical in shape. The Curie temperature measurements revealed that compositions of the KLN51.5 and KLN50 fibers did not coincide with that of the ceramic source rods
