氧化铈

氧化铈用途

【用途一】
用作分析试剂、氧化剂和催化剂
【用途二】
用于制备抛光粉和汽车尾气催化剂
【用途三】
用作玻璃工业添加剂，作板玻璃研磨材料，目前已扩大到眼镜玻璃、光学透镜、显像管的研磨，起脱色、澄清、玻璃的紫外线和电子线的吸收等作用。也作眼镜透镜的防反射剂，与铈制成铈钛黄使玻璃呈浅黄色。用于陶瓷釉料及电子工业中，作为压电陶瓷渗人剂。还用于制造高活性催化剂，煤气灯白炽罩，x射线用荧光屏。
【用途四】
高效催化剂，精密抛光，化工助剂，电子陶瓷，结构陶瓷，紫外线收剂，电池材料等。

氧化铈制备

以氯化铈或硝酸铈为原料，用氨水调节pH值为2，加入草酸沉淀出草酸铈，经加热熟化、分离、洗涤，在 110 ℃ 下烘干，再于900～1000℃灼烧成二氧化铈。在一氧化碳气氛中， 1250 ℃ 温度下加热二氧化铈和碳粉的混合物即可制得三氧化二铈。
