Method for producing cerium-based polishing material and cerium-based polishing material produced by said method |
| abstract |
This invention is a method for producing a cerium-based abrasive whichnincludes: a step of grinding raw material for the cerium-based abrasive; a stepnof roasting the ground raw material; and a step of subjecting the roasted rawnmaterial to wet processing, the method being characterized in that it furthernincludes a lower-temperature re-roasting step of heating the wet-processed rawnmaterial at 200 to 700°C. In the invention disclosed in this application, annabrasive with particularly preferable properties can be produced by fullyndrying the wet-processed raw material in a drying step, and subsequentlynsubjecting the dried raw material to the lower-temperature re-roasting step. |
