Abstract:
The present invention relates to sintered abrasive grit agglomerates based on aluminum oxide, having homogeneously distributed nanoscale pores in the range of 100-300 nm, with a pore volume of at least 15%. The average diameter of primary particles of the aluminum oxide primary particles is less than 5 μm, wherein said primary particles are connected to each other without additional adhesive agent.
