Neodymium (III) Oxidekapena neodymium sesquioxide ndi mankhwala opangidwa ndi neodymium ndi mpweya ndi formula Nd2O3. Imasungunuka mu asidi ndipo imasungunuka m'madzi. Amapanga makristasi opepuka amtundu wa buluu wa hexagonal. The rare-earth mix didymium, yomwe poyamba ankakhulupirira kuti ndi chinthu, pang'ono imakhala ndi neodymium(III) oxide.
Neodymium oxidendi gwero la neodymium losasungunuka kwambiri lomwe silingasungunuke ndi magalasi, optic ndi ceramic. Mapulogalamu oyambirira amaphatikizapo ma lasers, magalasi opaka utoto ndi tinting, ndi dielectrics.Neodymium Oxide imapezekanso mu pellets, zidutswa, sputtering targets, mapiritsi, ndi nanopowder.
