三氧化二釹(化學式:Nd2O3),又稱氧化釹(Ⅲ),是的+3價氧化物。它是淡蓝色的潮解性六方结晶,[1]難溶于水,能溶于酸。被误认为是化学元素的稀土混合物 didymium含有三氧化二钕。[2]

制备

三氧化二钕可以由氮化钕氢氧化钕在空气燃烧而成。[3]

用途

三氧化二钕可以用来制作涂料玻璃,包括太阳眼镜、制造固态激光英语solid-state laser、以及为玻璃和搪瓷涂色[4] 一些含钕涂料玻璃吸收黄光和绿光,所以是紫色的,也可以用于焊接护目镜[5] 一些含钕涂料玻璃是双色性英语dichroic的,也就是会随着光照而改变颜色。 一种以矿物alexandrite英语alexandrite命名的玻璃在阳光下为蓝色,在人造光源下为红色。[6]全世界每年生產約7000噸的三氧化二釹,可用來染色玻璃和陶瓷材料,製取光学玻璃和激光元件。三氧化二钕也可以用做聚合反应催化剂[5]
