Abstract
The present invention provides a cerium-based abrasive slurry particles including a cerium-based abrasive particle of no less than 95% by weight of total rare earth oxides (TREO), in which the cerium-based abrasive particle has less than 3% by weight of fluorine content of TREO, and a particle size distribution determined by a laser diffraction method is within a predetermined range. And adhesion property is further improved by setting this fluorine content in 0.005 to 0.5% by weight of TREO.
