ABSTRACT:
A method is provided whereby high brightness metaborate phosphors are made by milling the reactants in a saturated aqueous solution of magnesia and boric acid prior to firing. The method increases the homogeneity of the fired metaborate phosphor cake and reduces the tendency of the fired cake to stick to the firing boats.
