Preparation method of nano aluminium nitride powder
The invention discloses a preparation method of nano aluminium nitride powder, belonging to the technical field of nano material preparation. The preparation method comprises the following steps: preparing a solution according to a certain proportion by adopting aluminium sources, water-soluble carbon sources and assistant agents as raw materials; heating the solution, so that the solution is decomposed after being volatilized and concentrated, thus obtaining precursor powder; reacting the precursor powder in a certain atmosphere at 1200-1800 DEG C for 1-5 hours; treating the powder after reaction in the air at 500-800 DEG C for 1-3 hours, thus obtaining the nano aluminium nitride powder. The preparation method is simple in process and low in cost and can be used for obtaining the nano aluminium nitride powder which has good degree of sphericity and dispersibility and has a particle size smaller than 50nm.
