The present invention relates to a low-temperature synthesis method of aluminum nitride and, more specifically, to a method for synthesizing aluminum nitride by: heating and degreasing feed stock granules, which is made by pressing and kneading a mixture powder containing 0.5-8 wt% of a zinc powder, 0.01-2 wt% of a magnesium powder, 0.01-1 wt% of a silicon powder, 0.01-1 wt% of a copper powder, and the remainder aluminum powder, together with an organic binder, or a molded body prepared from the feed stock granules in the nitrogen gas atmosphere at normal pressure, thereby preparing a porous body; and then inducing a rapid nitride reaction of the aluminum powder. Further, the present invention relates to a method for synthesizing a composite substance with a high content of aluminum nitride, by further adding at least one inorganic material, which is selected from the group consisting of lithium, calcium, phosphor, gadolinium, iron, nickel, cobalt, manganese, silver, chrome, zirconium, strontium, molybdenum, tungsten, and alloys thereof or Al_2O_3, SiO_2, ZrO_2, CaO, Y_2O_3, TiC, TiN, B_4C, SiC, Si_3N_4, TiB_2, h-BN, c-BN, diamond, carbon nanotubes, and graphene, to the aluminum mixed powder, and then sintering the mixture in the nitrogen gas atmosphere. |
