三氧化二钕 Neodymium(III) oxide
（重定向自Neodymium sesquioxide）
三氧化二钕（化学式：Nd2O3），又称氧化钕（Ⅲ），是钕的+3价氧化物。它是淡蓝色的潮解性六方结晶，难溶于水，能溶于酸，在空气中加热时部分变成钕的高价氧化物。

Neodymium(III) oxide or neodymium sesquioxide is the chemical compound composed of neodymium and oxygen with the formula Nd2O3. It forms very light grayish-blue hexagonal crystals. The rare earth mixture didymium, previously believed to be an element, partially consists of neodymium(III) oxide.
