Step method for preparing nano structure Li3NbO4 disclosed by the invention is as follows: 1) by KOH, Nb2O5 and deionized water as raw material, the synthesis of KNbO3 nanowires prepared by hydrothermal method; 2) KNbO3 nanowire and Li2CO3 powder prepared by the above 1.5 molar ratio of grinding and mixing, mixing after joining KCl powder and mixed powder weight, further grinding and uniformly mixing; 3) step 2) powder mixed in a muffle furnace, at 600~900 deg. 10~1000min insulation, fully cleaned with deionized water, dried. This method is simple and easy to operate, the available raw materials, recycling, short preparation period and high yield; nano structure of Li3NbO4 with high purity, controllable morphology, uniform size, can be widely used in nano structure microwave dielectric ceramics, optical ceramic materials and nano fluorescent powder etc..
