Preparation method of aluminum nitride nano powder based on continuous gas phase activation
The invention relates to a preparation method of aluminum nitride nano powder based on continuous gas phase activation, and relates to the technical field of preparation of aluminum nitride nano powder. The preparation method comprises the following steps: 1, adding an ethanol solution of aluminum chloride hexahydrate into an ethanol solution of urea in batches, stirring, cooling, filtering, and drying the obtained solid to obtain an Al [(CON2H4) n] Cl3 precursor, n being 3-6; 2, placing a first crucible containing the Al [(CON2H4) n] Cl3 precursor in a constant temperature section of a tubular heating furnace; a second crucible containing melamine is placed on the non-constant-temperature section, close to one side of the gas inlet, of the tubular heating furnace; reacting in a nitrogen atmosphere at 1000-1400 DEG C to obtain aluminum nitride coarse powder; and 3, decarbonizing the aluminum nitride coarse powder to obtain the aluminum nitride nano powder.
