Preparation method of solid spherical aluminum oxide granulation powder
The invention discloses a preparation method of solid spherical aluminum oxide granulation powder, which comprises the following steps: firstly, adding a specific anionic surface activity dispersing agent to disperse and mix aluminum oxide powder and a sintering aid, and then adding a specific cationic surface activity dispersing agent to neutralize surface charges of the anionic surface activity dispersing agent to obtain aluminum oxide slurry; according to the preparation method, the mixing uniformity of the aluminum oxide powder and the sintering aid can be ensured, and the aluminum oxide slurry can be in a solid sphere shape after being granulated.
本发明公开一种实心球形氧化铝造粒粉的制备方法，先添加特定的阴离子表面活性分散剂将氧化铝粉和烧结助剂进行分散混合，后添加特定的阳离子表面活性分散剂用来中和阴离子表面活性分散剂的表面电荷，得到氧化铝浆料，最后喷雾造粒得到实心球形氧化铝造粒粉，通过此制备方法，既可以保证氧化铝粉和烧结助剂混合的均匀性，又能实现氧化铝浆料造粒后呈现实心球形。
