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.
