A shaped ceramic abrasive particle, in particular on the basis of alpha-AlO, includes at least three faces, at least two faces of which form a common vertex on which at least one corner common to the three faces lies. The abrasive particle has at least one structural weakening element. The disclosure also relates to an abrasive article including the abrasive particles, and a method for producing the abrasive particles.

Shaped ceramic abrasive particle and method for producing a shaped ceramic abrasive particle

An abrasive particle includes at most three surfaces and at least one edge which has a corner at at least one end. The abrasive particle may contain a ceramic material, particularly polycrystalline &#x3b1;-AlO. Abrasive particles as a whole, methods for producing abrasive particles, moulds, abrasive articles, methods for producing abrasive articles, and methods for abrading a surface are also disclosed.

Abrasive particle with at most three surfaces and one corner

An abrasive grain includes a surface having at least a first face with a first outline, and at least one second face with a second outline. The first outline does not contain any vertices, but the second outline contains at least one vertex. The abrasive grain may include a ceramic material, especially polycrystalline &#x3b1;-AlO.

Abrasive grain with main surfaces and subsidiary surfaces

An abrasive particle includes at most three surfaces and at least one edge which has a corner at least one end. The abrasive particle may contain a ceramic material, particularly polycrystalline &#x3b1;-AlO. Abrasive particles as a whole, methods for producing abrasive particles, moulds, abrasive articles, methods for producing abrasive articles, and methods for abrading a surface are also disclosed.
