Preparation method of aluminum nitride/boron nitride composite ceramic powder
The invention discloses a preparation method of aluminum nitride/boron nitride composite ceramic powder, and belongs to the technical field of preparation of ceramic powder. The preparation method comprises the following specific steps of with aluminum source, boron source, amine organism, waters soluble carbon source and assistant agent as raw materials, preparing a solution according to a certain ratio, heating and stirring, volatilizing and concentrating the solution, and reacting to obtain precursor powders; reacting the precursor powders for 2-4h in a flowing nitrogen atmosphere at 1300-1700 DEG C, heating the reacted powders for 1-3h in air at 500-650 DEG C so as to obtain the aluminum nitride/boron nitride composite ceramic powder. The preparation method is applicable for synthesizing high-purity high-dispersion and high fine granularity under a lower reaction temperature condition, the operation is simple, the cost is low, and the industrial production is prompted.
