Li_(2)B_(4)O_(7) and LiNbO_(3) single crystals were grown by the pulling-down(PD) method. By the method, single crystals can be easily obtained by solidifying the melt flowing out of a hole at the bottom of a crucible. The bubble free Li_(2)B_(4)_O_(7) crystals were obtained by using the PD method. Dislocation density was estimated to be about 1～5×10~(4)cm~(-2), which was somewhat more than that obtained by other methods. Crack free LiNbO_(3) crystals have also successfully grown by the PD method. The as-grown crystals were trans-parent with slightly yellow in color. The crystals had stoichi-ometric composition because of feeding stoichiometric powder.
