Method for producing an abrasive particle, and abrasive particle

The invention relates to a method for producing an alumina based abrasive particle (1), comprising at least the following steps:forming a sol as a solution or dispersion of alumina particles,gelling the sol by adding gelling agents,forming shaped bodies from the gel using an additive procedure,drying and firing the shaped bodies while retaining the previously achieved geometry of the abrasive particles.Hereby, it is provided thatan optically binding binder is added to the sol and/or the gel,the gel is applied additively layer by layer and the binder is set using electromagnetic radiation so as to form the shaped bodies.The produced abrasive particle may be formed, in particular, by six intersecting or overlapping triangular volume regions.
