| titleOfInvention | Method of manufacturing alumina-based abrasive grain and alumina-based abrasive grain manufactured thereby |
| abstract | Provided are a method of manufacturing an alumina-based abrasive grain, which includes preparing boehmite powder and activated alumina powder as starting materials, forming a sol by wet-blending and crushing the boehmite powder, the activated alumina powder, a solvent and a deflocculant, heating the sol at a first temperature which is higher than a room temperature and lower than a boiling point of the solvent and stirring the sol so as not to generate a precipitate, forming a gel by heating the sol at a second temperature higher than the first temperature at which a viscosity of the sol is increased and the sol becomes a paste, blending the gel with an organic solvent and performing wet crushing on the resulting mixture, preparing a powder by drying the wet-crushed gel, blending a binder and a solvent with the dried product, which is the powder, and molding the resulting mixture, calcining the molded product, performing dry crushing on the calcined product, and sintering the dry-crushed product to transform activated alumina and boehmite contained therein to an α-Al 2 O 3 crystal phase, and an alumina-based abrasive grain manufactured thereby. As a result, an alumina-based abrasive grain which is highly dense, has a high hardness, and exhibits a high purity may be manufactured using boehmite powder and activated alumina powder. |
