Preparation method of aluminum nitride powder and aluminum nitride powder
The invention provides an aluminum nitride powder preparation method and aluminum nitride powder, and relates to the technical field of ceramic materials. The preparation method of the aluminum nitride powder comprises the following steps: dispersing lactose and aluminum oxide in deionized water to obtain a mixed solution; stirring and heating the mixed solution to obtain jelly; heating the jelly, and carrying out foaming and curing processes on the jelly to obtain a reaction precursor; and sequentially carrying out carbon thermal reduction nitridation treatment in a nitrogen atmosphere and decarburization treatment in an air atmosphere on the reaction precursor to obtain the aluminum nitride powder. The preparation method of the aluminum nitride powder is simple in process, and the prepared aluminum nitride powder is high in quality.
本公开提供了一种氮化铝粉体制备方法和氮化铝粉体，涉及陶瓷材料技术领域。该氮化铝粉体制备方法包括：将乳糖和氧化铝分散于去离子水中，以得到混合溶液；对混合溶液进行搅拌并加热，以得到胶状物；对胶状物进行加热，使胶状物经发泡和固化过程，以得到反应前驱体；对反应前驱体依次进行氮气气氛中的碳热还原氮化处理以及空气气氛中的脱碳处理，以得到氮化铝粉体。本公开的氮化铝粉体制备方法工艺简单，且制备出的氮化铝粉体质量高。
