Tetragonal tungsten-bronze potassium lithium niobate crystals (KLN) were grown by vertical Bridgman technique. Transparent KLN crystals with 10 mm in diameter and 25 to 45 mm in length were obtained. Crystallization behavior from different KLN melts was studied. It was found that KLN crystals will stop growing after the melt composition changes to some critical value and other phases, such as KNbO3, LiNbO3 and Li3NbO4, crystallize at the same time. Inhomogeneity and cleavage of as-grown KLN crystals were discussed.
