Preparation method of aluminum nitride nano powder based on dual activation
The invention relates to a preparation method of aluminum nitride nano powder based on dual activation, and relates to the technical field of preparation of nano aluminum nitride. The method comprises the following steps: 1, mixing an aluminum source, a carbon source and an in-situ activator according to a molar ratio of 1: (0-5): (0.1-5) to obtain a reaction precursor; the in-situ activating agent is melamine; 2, placing the reaction precursor in a first crucible, and placing the first crucible in a constant temperature section of a tubular heating furnace; an ex-situ activator melamine is placed in a second crucible, and the second crucible is placed on a non-constant-temperature section, close to one side of the gas inlet, of the tubular heating furnace; the mass ratio of the reaction precursor to the ex-situ activator is 1: (0.5-5); carrying out a carbon thermal reduction reaction in a nitrogen atmosphere at 1000-1500 DEG C to obtain mixed powder; and 3, decarbonizing the mixed powder to obtain the aluminum nitride nano powder.
