| abstract |
The present invention relates to a method for producing abrasive particles comprising the steps of: i. preparing a starting mixture containing at least aluminum hydroxide, wherein the mixture can be converted to at least aluminum oxide by heat treatment; ii. extruding the starting mixture to form an extrudate; iii. separating the extrudate into intermediate particles; and iv. heat treating the intermediate particles, wherein the intermediate particles are converted into abrasive particles containing aluminum oxide, wherein the extrudate and/or the intermediate particles have a geometry of the extrudate and/or the intermediate particles. It is given an energy input that is asymmetric with respect to the structure. |
