Abstract: A rare earth borate in the form of substantially spherical, uniform diameter particles having an average particle diameter of 0.5-2 &mgr;m is prepared by mixing substantially spherical rare earth oxide co-precipitates having an average particle diameter of 0.5-2 &mgr;m with boric acid or boron oxide, and heating the mixture at 600-1100° C. for reaction. It is a useful raw material for phosphor manufacture.
