Patent ID: 6893477

Claim:
An abrasive slurry including abrasive particles containing cerium, no less than 95% by weight of total rare earth oxides (TREO) and less than 3% by weight of fluorine relative to TREO, wherein the abrasive particles have a cumulative 10% particle diameter (D 10 ) of no less than 0.1 μm and no greater than 0.6 μm, a cumulative 50% particle diameter (D 50 ) of no less than 0.2 μm and no greater than 1.0 μm, a cumulative 90% particle diameter (D 90 ) of no less than 0.3 μm and no greater than 1.5 μm, and a maximum particle diameter (D max ) of no less than 0.5 μm and no greater than 5.0 μm, and wherein D 10 , D 50 , D 90 and D max are measured by a laser diffraction method.
