摘要： The object of the present invention is to provide a powder cerium-based abrasive which enables the preparation of a cerium-based abrasive slurry, in which the dispersed state of the abrasive particles is maintained for a long period of time, simply by blending it with a dispersion medium such as water and which makes easier the after-treatment of the abrasive slurry having been used. The cerium-based abrasive of this invention is a cerium-based abrasive including chlorine-containing compounds in which chlorine (element) is contained in amounts, in terms of total mass, equivalent to 0.05% to 5.0% of the mass of the total rare earth oxide contained therein. An abrasive slurry including the abrasive of this invention as a solid content is superior in dispersion maintaining properties of its abrasive particles. Accordingly, an abrasive slurry having a stable concentration of the solid content can be supplied continuously. Further, the abrasive requires no dispersant for maintaining its dispersed state, and hence separation treatment for a dispersant is unnecessary after the abrasive has been used. Thus, the abrasive according to the present invention makes simpler the after-treatment of the abrasive slurry after use.

摘要： Regarding a cerium oxide-based abrasive containing cerium oxide as a main component and abrasive particles with an average particle diameter of 0.2 to 3.0 &mgr;m, the present invention provides a cerium-based abrasive containing coarse particles of 10 &mgr;m or larger in a concentration of 1000 ppm or lower (by weight) or magnetic particles in a concentration of 1000 ppm or lower (by weight). The coarse particles or the magnetic particles are particularly preferable to exist in a concentration of 300 ppm or lower (by weight). Further, by controlling an average value of the specific surface area of the abrasive particles to be within 0.5 to 30 m2/g, the resulting abrasive is provided with a high cutting property and is capable of forming a polished face with high precision. The production method of such cerium-based abrasives comprises control being the concentration of the coarse particles and the classification point and repeated classification. The control of the magnetic particle concentration is made possible by utilization of a filter of a magnetic material and alteration of pulverization media, which are either solely or properly combined with each other to be performed.
