Crucible for melting rare earth element alloy and rare earth element alloy
The present invention provides a crucible containing, as primary components, one or more selected from rare earth element oxides including Y2O3 and Al2O3, which is prepared through the firing at 500 to 1800 DEG C. Such that the rare earth element oxide is distributed in a finer part of a material for the firing having a particle diameter of 0.5 mm or less in a percentage higher than that of a coarser part of the material having a particle diameter of greater than 0.5 mm, and that it contains substantially no reaction products of the above rare earth element oxide with the at least one of Al2O3 and Al2TiO5; and a rare earth element alloy produced by the use of the crucible.
