日本稀土学会主席认为:1.由于占全部稀土消耗量94%的触媒、治金、玻璃工业对稀土的需要市场萎缩,而只占6%的高技术市场(磁铁、萤光材料等)需要增长,因而促进Ce、La等轻稀土过剩的所谓不平衡, The president of the Japan Society of Rare Earth thinks: 1. Due to the catalyst of 94% of the total rare earth consumption, the demand for rare earth by the metallurgical and glass industries is shrinking. Only 6% of the high-tech markets (magnets, fluorescent materials, etc.) need to grow , Thus promoting the so-called imbalance of light rare earths such as Ce and La,
