METHOD FOR SETTING FIRING TEMPERATURE OF CERIUM CARBONATE, METHOD FOR PRODUCING CERIUM OXIDE ABRASIVES AND CERIUM OXIDE ABRASIVES OBTAINED BY THE METHOD

摘要

A method for producing a cerium oxide abrasive, characterized in that the method comprises firing a raw material of cerium carbonate having a fluorine content F (ppm by mass) falling within a range of 10 to 500 ppm by mass, at a firing temperature T (°C) selected within a temperature range defined by the following formula: 730 - 14[log(F)] <= T <= 790 - 10[log(F)].
