Abstract
The present invention relates to sintered shaped abrasive grains on basis of aluminum oxide. Sintered shaped abrasive grains consistent with the disclosure include mineralogical phases made of mullite, tialite and/or armalcolite, and baddeleyite and/or srilankite. Methods for producing sintered shaped abrasive grains using alumina, ilmenite and zircon sand as raw materials are also provided.
