ABRASIVE PARTICLES, METHOD OF OBTAINING ABRASIVE PARTICLES AND ABRASIVE ARTICLES Russian patent published in 2017 - IPC B24D3/14 C09C1/68 C09G1/02 C09K3/14 

FIELD: technological processes.

SUBSTANCE: moulded ceramic abrasive particle comprises the first surface, the second surface and a peripheral surface. The first surface has a perimeter consisting of the first and the second edges. The first perimeter area comprises the second edge and extends inwards, ending at the two vertices forming the first and the second internal acute angles. Wherein the perimeter comprises four vertices forming internal acute angles. The second surface is positioned opposite the first and does not come in contact with it. The peripheral surface is positioned between the first and the second surfaces, joining them. The peripheral surface comprises the first wall contacting with the perimeter at the first edge and the second wall contacting with the perimeter at the second edge.

EFFECT: higher efficiency of abrasive processing.
