Abstract

L'invention concerne des particules abrasives constituées de céramique (y compris des verres, des céramiques cristallines, et des vitrocéramiques) contenant (sur une base d'oxyde théorique) de l'Al2O3 et au moins un autre oxyde métallique (par exemple du REO et; du REO et au moins du ZrO2 ou du HfO2) et leurs procédés de production. Lesdites particules abrasives peuvent être incorporées à une variété d'articles abrasifs, notamment des abrasifs agglomérés, des abrasifs appliqués, des abrasifs non-tissés, et des brosses abrasives.The invention relates to abrasive particles made of ceramic (including glasses, crystalline ceramics, and glass ceramics) containing (on a theoretical oxide basis) Al2O3 and at least one other metal oxide (e.g. REO and; REO and at least ZrO2 or HfO2) and their production processes. Said abrasive particles can be incorporated into a variety of abrasive articles, including bonded abrasives, applied abrasives, nonwoven abrasives, and abrasive brushes.
