Lithium tantalate, LiTaO 3 (LT), single crystal growth by the vertical Bridgman (VB) technique is attempt for the first time. In the present VB‐LT technique, pure platinum crucibles are used in a furnace with a graphite heater and an argon atmosphere. One‐hundred percent solidified crack‐free VB‐LT crystals are successfully grown by composing the initial melts with exactly congruent compositions. The fundamental technical issues for VB‐LT growth are also clarified.
