| titleOfInvention | Preparation method of completely dispersed aluminum oxide nanoparticles |
| abstract | The invention discloses a preparation method of completely dispersed alumina nano particles. The method adopts a high-energy ball milling method to directly mill the commercial gamma alumina powder, atmosphere protection is not needed in the ball milling process, impurities from a ball milling tank and a ball milling medium in the powder are removed through room-temperature acid corrosion, and high-temperature corrosion of a reaction kettle is not needed, so that the completely dispersed, non-agglomerated and fine-particle alumina nano-particles with complete dispersion, no agglomeration, fine particle size and purity of 99.994 wt.% are obtained. The method has the advantages of cheap raw materials, simple process, simple and convenient operation, low cost, strong repeatability, high yield, large yield, easy batch preparation and the like, and lays a foundation for the direct application of the alumina nano particles and the preparation and research of the alumina nano-crystalline ceramics. |
