Abstract
This invention is a method for producing a cerium-based abrasive which includes: a step of grinding raw material for the cerium-based abrasive; a step of roasting the ground raw material; and a step of subjecting the roasted raw material to wet processing, the method being characterized in that it further includes a lower-temperature re-roasting step of heating the wet-processed raw material at 200 to 700° C. In the invention disclosed in this application, an abrasive with particularly preferable properties can be produced by fully drying the wet-processed raw material in a drying step, and subsequently subjecting the dried raw material to the lower-temperature re-roasting step.
