ZIRKONKORUND-SCHLEIFKÖRNER MIT HOHEM SIO2-ANTEIL
The present invention relates to abrasive zirconium corundum grains based on Al2O3 and ZrO2 that have been melted in an electrical arc furnace and have a content of—Al2O3 between 52% and 62% by weight,—ZrO2 (+HfO2) between 35.0% and 45.0% by weight, where a total of at least 80% by weight of the ZrO2, based on the total content of ZrO2, is in the tetragonal and/or cubic high-temperature modification,—Si compounds of more than 0.8% by weight, expressed as SiO2,—carbon between 0.03% and 0.5% by weight,—additives between 0.5% and 10% by weight and—raw material-related impurities of less than 3% by weight, where the raw material base for the abrasive grains comprises aluminum oxide, baddeleyite and zircon sand.
