Beschreibung
Zusammenfassung:	The invention relates to a shaped ceramic abrasive particle, on the basis of alpha-Al2O3 and containing a proportion of 5 wt.-% to 30 wt.-% of ZrO2, the alpha-Al2O3 having a medium crystallite size of0.5 [mu]m to 3 [mu]m and the ZrO2 having a medium crystallite size of 0.25 [mu]m to 8 [mu]m. The invention also relates to an abrasive article comprising the abrasive particles and to a method for producing the abrasive particles. 本发明涉及一种成形陶瓷磨粒，该成形陶瓷磨粒在α-AlO的基础上包含5％重量百分比至30％重量百分比含量的ZrO，其中，α-AlO的平均晶粒尺寸为0.5μm至3μm并且ZrO的平均晶粒尺寸为0.25μm至8μm，以及具有这样的磨粒的磨削用品和用于制造这种磨粒的方法。
