Lutetium(III) Oxide(Lu2O3), i kapa ʻia ʻo lutecia, he paʻa keʻokeʻo a me kahi hui cubic o lutetium. He kumu Lutetium kūpaʻa ʻole loa ia, nona kahi ʻano aniani cubic a loaʻa i ka ʻano pauka keʻokeʻo. Hōʻike ʻia kēia ʻano metala metala koʻikoʻi, e like me kahi helu heheʻe kiʻekiʻe (ma kahi o 2400°C), paʻa paʻa, ikaika mechanical, paʻakikī, conductivity thermal, a me ka hoʻonui wela haʻahaʻa. He kūpono ia no nā aniani kūikawā, optic a me nā noi ceramic. Hoʻohana ʻia ia e like me nā mea waiwai nui no nā kristal laser.
