Europium(III) Oxide (Eu2O3)ndi mankhwala a europium ndi mpweya. Europium oxide ilinso ndi mayina ena monga Europia, Europium trioxide. Europium oxide ili ndi mtundu woyera wa pinki. Europium oxide ili ndi mitundu iwiri yosiyana: cubic ndi monoclinic. Cubic yopangidwa ndi europium oxide imakhala yofanana ndi mawonekedwe a magnesium oxide. Europium oxide imakhala ndi kusungunuka kosasunthika m'madzi, koma imasungunuka mosavuta mu mineral acid. Europium oxide ndi chinthu chokhazikika chomwe chimakhala ndi malo osungunuka pa 2350 oC. Mphamvu zambiri za Europium oxide monga maginito, kuwala ndi luminescence zimapangitsa kuti zinthu izi zikhale zofunika kwambiri. Europium oxide imatha kuyamwa chinyezi ndi carbon dioxide mumlengalenga.
