Application Summary AI generated
This standard specifies a chemical analysis method for determining the content of 13 rare earth oxide impurities (from lanthanum to lutetium) in yttrium-europium oxide. It is applied in the metallurgical and rare earth industries for quality control of phosphor-grade raw materials, specifically the red-emitting component used in fluorescent lamps, LED displays, and cathode ray tubes. The method ensures the purity of the yttrium-europium oxide product by quantifying trace contaminants that can affect luminescent efficiency and color performance.
