放射性（Radioactive）

說明：淡黃色粉末，不溶于水和酸。

用途：用于玻璃脫色劑，玻璃拋光劑，也是制備金屬鈰的原料。高純度氧化鈰在稀土發(fā)光材料中有重要應(yīng)用。

Description: light yellow powder, insoluble in water and in acids

Uses: Mainly used as the glass decolorizing agent and the glass polishing powder. Also used as the raw material in making metal cerium. High purity Cerium dioxide is very important in the applications of rare earth fluorescent materials.
