Abstract (en)
[origin: DE19945335A1] The invention relates to a method for producing A12O3/SiC nanocomposite abrasive grains. SiC nanoparticles are added to a sol containing aluminium oxide and said sol is then gelatinized, dried, calcinated and sintered. The invention also relates to A12O3/SiC nanocomposite abrasive grains.
