Abstract
Abrasive slurries, abrasive articles made from the abrasive slurries, and methods for the production of the abrasive articles are disclosed. The abrasive slurries and abrasive articles made therefrom comprise at least two grades of abrasive particles (i.e., a first larger grade, and a second smaller grade). The abrasive grades have a median particle size ratio of about 2, where the median particle size ratio equals the median particle size of the larger grade of abrasive particles divided by the median particle size of any smaller grade of abrasive particles.
