The history of research and development of the Na flux method for GaN single crystal growth from its discovery in 1994 until now are summarized. Today this method becomes one of the important growth measures of high quality GaN crystals. The development of the Na flux method starting from clarification of the growth mechanism, then, showing a method of controlling nucleation by adding carbon, reporting a high quality crystallization technique by using solution stirring, and, finally, latest data on the point seeding are described.
