A method for manufacturing a fine particle containing a rare earth element comprising a first process of doping the rare earth element to at least one kind of basic carbonate selected from the group of basic yttrium carbonate, basic gadolinium carbonate, basic lutetium carbonate, basic lanthanum carbonate and basic scandium carbonate; and a second process of calcinations of the basic carbonate doped with the rare earth element. In the second process the basic carbonate doped with the rare earth element may be quenched after calcinations by a rapid heating. |
