Lutetiumhe mea laha 'ole ka honua me ke kumukuai ki'eki'e, ka li'ili'i o ka ho'ohana 'ana. He palupalu a hiki ke hoʻoheheʻe ʻia me ka wai.
Aia ka 175Lu a me ka hapalua o ke ola o 2.1 × 10 ^ 10 makahiki β Emitter 176Lu i nā isotopes maoli. Hana ʻia ia ma ka hoʻemi ʻana i ka Lutetium(III) fluoride LuF ∨ · 2H ₂ O me ka calcium.
ʻO ka hoʻohana nui ma ke ʻano he catalyst no ka petroleum cracking, alkylation, hydrogenation, a me nā hopena polymerization; Eia kekahi, hiki ke hoʻohana ʻia ʻo Lutetium tantalate e like me ke ʻano o ka pauka fluorescent X-ray; 177Lu, he radionuclide, hiki ke hoʻohana ʻia no ka radiotherapy o nā ʻōpū.

Ua ʻike ʻia e: G. Urban
Ua ʻike ʻia i ka makahiki 1907
Ua hoʻokaʻawale ʻia ʻo Lutetium mai ka ytterbium e ka mea lapaʻau Farani ʻo Ulban i ka makahiki 1907 a ʻo ia hoʻi kahi ʻano honua laha ʻole i ʻike ʻia a hoʻopaʻa ʻia i ka hoʻomaka ʻana o ke kenekulia 20. ʻO ka inoa Latin no lutetium mai ka inoa kahiko o Paris, Farani, ʻo ia ka wahi hānau o Urban. ʻO ka loaʻa ʻana o ka lutetium a me nā mea ʻē aʻe ʻē aʻe ʻo europium i hoʻopau i ka ʻike ʻana i nā mea ʻano honua like ʻole i ke ʻano. Hiki ke noʻonoʻo ʻia ko lākou ʻike ʻana ma ke ʻano he wehe ʻana i ka ʻīpuka ʻehā i ka ʻike ʻana i nā mea ʻenekele honua a me ka hoʻopau ʻana i ka pae ʻehā o ka ʻike ʻana i nā mea ʻene honua.

ʻO Lutetium kahi metala keʻokeʻo kālā, ʻo ia ka mea ʻoi aku ka paʻakikī a me ka ʻoi loa o ka metala ma waena o nā mea ʻeleʻele; Ka helu heheʻe 1663 ℃, kahi e hoʻolapalapa ai 3395 ℃, mānoanoa 9.8404. Paʻa ka Lutetium i ka lewa; He aniani kala ʻole ʻo Lutetium oxide e hoʻoheheʻe ʻia i loko o nā waikawa e hana i nā paʻakai kala ʻole.
Aia ma waena o ke kālā a me ka hao ka lutetium metallic earth luster. He hopena koʻikoʻi ka maʻiʻo haumia i ko lākou mau waiwai, no laila he mau ʻokoʻa koʻikoʻi ko lākou mau waiwai kino i ka palapala.
ʻO ka yttrium metala, ka gadolinium, a me ka lutetium he kūpaʻa kūpaʻa ikaika a hiki ke mālama i ko lākou luster metala no ka manawa lōʻihi.

Ma muli o nā pilikia hana a me nā kumukūʻai kiʻekiʻe, he liʻiliʻi ka hoʻohana ʻana o ka lutetium. ʻAʻole ʻokoʻa loa nā waiwai o ka lutetium mai nā metala lanthanide ʻē aʻe, akā ʻoi aku ka liʻiliʻi o kona mālama ʻana, no laila ma nā wahi he nui, hoʻohana mau ʻia nā metala lanthanide e pani i ka lutetium.
Hiki ke hoʻohana ʻia ʻo Lutetium e hana i kekahi mau alloys kūikawā, e like me ka Lutetium alumini alumini hiki ke hoʻohana ʻia no ka neutron activation analysis. Hiki ke hoʻohana ʻia ʻo Lutetium ma ke ʻano he catalyst no ka petroleum cracking, alkylation, hydrogenation, a me nā hopena polymerization. Eia kekahi, ʻo ka doping lutetium i kekahi mau kristal laser e like me Yttrium alumini garnet hiki ke hoʻomaikaʻi i kāna hana laser a me ka like ʻole o ka optical. Eia kekahi, hiki ke hoʻohana ʻia ka lutetium no nā phosphors: ʻO Lutetium tantalate ka mea keʻokeʻo paʻa loa i ʻike ʻia i kēia manawa, a he mea kūpono no nā phosphors X-ray.
ʻO 177Lu kahi radionuclide synthetic, hiki ke hoʻohana ʻia no ka radiotherapy o nā ʻōpū.
