N2 - LiNbO3 micro single crystals were succesfully grown by a crystal growth method using a micro nozzle in the bottom of a crucible. By this method, crack-free LiNbO3 single crystals have been grown along the x, y and z axes having diameters of 60-800 μ m, independent of the growth axis, growth rate and melt composition. Very high growth rates of up to 90 mm/h have been used without lessening of crystal quality. The grown crystals were revealed to be free of dislocations and subgrain boundaries up to 500 μ m in diameter, as determined by X-ray topography and etching technique.
