Preparation method of aluminum nitride powder
The invention provides a preparation method of aluminum nitride powder, which comprises the steps of: S1, weighing gamma-Al2O3 micro powder, carbon black, a dispersant, a binder, a catalyst, a biomass carbon source and water, and mixing to obtain precursor slurry; and performing spray granulation on the precursor slurry to obtain precursor granulation powder; S2, rotating the precursor granulation powder in a tubular furnace under nitrogen flow, and heating the precursor granulation powder for reaction to obtain raw aluminum nitride powder; and S3, carrying out decarburization treatment on the rawaluminum nitride powder in a decarburization atmosphere to obtain aluminum nitride powder.
本发明提供了一种氮化铝粉体的制备方法，包括如下步骤：S1称取γ‑Al2O3微粉，炭黑、分散剂、粘结剂、催化剂、生物质碳源和水混合，得到前驱体料浆；对所述前驱体浆料进行喷雾造粒，得到前驱体造粒粉；S2在氮气流下，于管式炉中，旋转所述前驱体造粒粉，并加热所述前驱体造粒粉使其发生反应得到氮化铝原粉；S3在脱碳气氛下对所述氮化铝原粉进行脱碳处理，即得。
