Title:
METHOD FOR PRODUCING AN ABRASIVE PARTICLE, AND ABRASIVE PARTICLE
Document Type and Number:
WIPO Patent Application WO/2018/010730
Kind Code:
A3
Abstract:
The invention relates to a method for producing an aluminium-based abrasive particle (1), at least comprising the following steps: forming a sol as a solution or dispersion of aluminium particles, gelling the sol by adding gelling agents, forming shaped bodies from the gel using an additive method, drying and firing the shaped bodies while retaining the previously achieved geometry of the abrasive particles. According to the invention, an optically binding binder is added to the sol and/or the gel and the gel is applied in layers in an additive manner, and the binder is set using electromagnetic radiation so as to form the shaped bodies. The abrasive particle obtained can be formed, in particular, by six intersecting or overlapping triangular volumetric areas.
