Spherical low-sodium aluminum oxide powder as well as preparation method and application thereof
The invention provides spherical low-sodium aluminum oxide powder as well as a preparation method and application thereof, and belongs to the technical field of aluminum oxide. The preparation method comprises the following steps: preparing porous submicron sphere-like alumina microspheres by adopting an ultrasonic-assisted sol-gel reaction, uniformly mixing with boric acid and aluminum chloride after steam sodium removal and wet sodium removal, and firing in a rotary kiln to prepare the submicron sphere-like low-sodium alumina powder. The product is uniform in structure and performance, economical, efficient and convenient for batch production, and after further ball milling, the obtained microspheres are approximately in a uniform sphere-like shape, are relatively low in sodium content and have a wide application prospect.
本发明提出了一种球形低钠氧化铝粉体及其制备方法和应用，属于氧化铝技术领域。采用超声波辅助溶胶凝胶反应制备多孔亚微米类球形氧化铝微球，经过蒸汽除钠、湿法除钠后，与硼酸和氯化铝混合均匀，回转窑烧制，制得亚微米类球形低钠氧化铝粉体。本发明产品结构、性能均一，经济高效，便于批量化生产，进一步经过球磨后，得到的微球大体呈均匀的类球形，且钠含量较低，具有广阔的应用前景。
