'''氧化铒'''，化学式為{{化學式|鉺|2|氧|3}}。

==性质==
粉红色粉末，不溶于水，可溶于[[酸]]：
: Er<sub>2</sub>O<sub>3</sub> + 6 H<sup>+</sup> → 2 Er<sup>3+</sup> + 3 H<sub>2</sub>O

==制备==
[[硫酸铒]]或[[硝酸铒]]溶液与[[氢氧化物]]溶液作用沉淀出[[氢氧化铒]]或其碱性盐，经分离、灼烧制得氧化铒。
:<math>\rm \ 2Er(OH)_3\rightarrow Er_2O_3+3H_2O</math>

==用途==
用作[[核反应堆]]的控制材料、[[钇铁石榴石]]的添加材料、玻璃的玫瑰红色着色剂。也用于制造吸收红外线和特种发光玻璃。
