Mea hoʻohui ʻia ka pauda lepo lāʻau metala Samarium pauda CAS 7440-19-9 Nā Alloy-Entropy kiʻekiʻe.

Hana ʻia ʻo Samarium ma ke ʻano he paʻa kala kala/foils a i ʻole ka pauda hina a he mea ʻala ʻole, paʻa ahi, a me ka wai-reactive paʻa. ʻIke ʻia nā ʻano like ʻole o ka samarium me ka hoʻoheheʻe ʻana i nā waikawa dilute e hoʻokuʻu ana i ke kinoea hydrogen flammable/explosive. Hoʻopili ʻo Samarium i ka wai a hoʻokuʻu i nā kinoea wela loa. ʻAʻole kūpono ʻo Samarium me nā ʻakika ikaika, nā mea oxidizing ikaika, a me nā halogens. ʻO ka noi pāʻoihana nui o ka samarium aia i nā magnet samarium-cobalt. Loaʻa i kēia mau mea magnetization waiwai mau. Ua hōʻike ʻia nā pūhui Samarium e kūpaʻa i nā mahana kiʻekiʻe loa, ma luna o 700 ° C, me ka ʻole o ka nalowale ʻana i kā lākou mau waiwai magnetic. ʻO ka radioactive isotope samarium-153 ka mea nui o ka lāʻau samarium 153Sm lexidronam (Quadramet). Hoʻohana ʻia kēia mau mea i ka mālama ʻana i nā maʻi maʻi o ke akemāmā, prostate, a me ka umauma a me ka osteosarcoma. Hoʻohana ʻia ʻo Samarium i ka catalysis o nā hopena kemika, radioactive dating, a me ka x-ray laser. Hoʻohana ʻia ʻo Samarium ma ke ʻano he catalyst i kekahi mau hopena kūlohelohe: Hoʻohana ʻia ʻo Samarium iodide (SmI2) e nā mea noiʻi noiʻi kūlohelohe e hana i nā mana synthetic o nā huahana kūlohelohe. Loaʻa ka Samarium me ka hoʻopaʻa ʻana a hiki i ka 2.8% i loko o kekahi mau minela me ka cerite, gadolinite, samarskite, monazite, a me ka kahua bastn? Loaʻa ka hapa nui o kēia mau mineral ma Kina, ʻAmelika Hui Pū ʻIa, Brazil, India, Sri Lanka, a me Australia; ʻO Kina ke alakaʻi nui o ka honua i ka mining samarium a me ka hana. ʻO ka radioactive isotope samarium-153 ka mea nui o ka lāʻau samarium (153Sm) lexidronam (Quadramet), e pepehi ana i nā maʻi maʻi maʻi i ka mālama ʻana i ka maʻi maʻi ʻaʻai, prostate cancer, breast cancer, a me osteosarcoma. ʻO ka isotope, samarium-149, he neutron absorber ikaika a no laila ua hoʻohui ʻia i nā koʻokoʻo mana o nā reactors nuklea. Hoʻohana ʻia ʻo Samaria oxide no ka hana ʻana i ke aniani infrared-adsorbing kūikawā a me nā cores o nā electrodes carbon arc-lamp oxide a ma ke ʻano he catalyst no ka dehydration a me ka dehydrogenation o ka ethanol. Hoʻohana ʻia kāna hui me ka cobalt (SmCo5) i ka hana ʻana i kahi mea magnet mau loa. ʻAʻohe kuleana o Samarium, akā ua ʻike ʻia e hoʻoulu i ka metabolism. ʻO nā paʻakai samarium hiki ke hoʻoheheʻe ʻia ma ka ʻai ʻana, a aia nā pōʻino olakino e pili ana i kēia mau mea no ka mea ʻo ka ʻike ʻana i ka samarium ke kumu o ka ʻili a me ka maka. ʻO kekahi o nā noi nui loa o ka samarium aia i loko o nā magnet samarium-cobalt, nona ka inoa inoa o SmCo5 a i ʻole Sm2Co17. Loaʻa iā lākou ka magnetization mau loa, ma kahi o 10,000 mau manawa o ka hao a ʻo ia ka lua o ka neodymium magnets. He mea maʻalahi ka Samarium i ka magnetize, akā paʻakikī loa ka demagnetize. ʻO kēia ka mea kūpono no ka hana ʻana i nā magnet mau loa (SmCo5) i ʻāpana o nā disks paʻakikī no nā kamepiula. Hoʻohana ʻia ʻo Samarium ma ke ʻano he neutron absorber i nā nuklea reactors, a me nā lasers andmetallurgical noiʻi. Hana ʻia ma kahi o 1% o nā metala i loko o ka metala misch, kahi huila i loko o nā pahu kukui cigarette. ʻO ia hoʻi kekahi o nā honua laha ʻole i hoʻohana ʻia i nā kukui a me nā kukui carbon-arc i hoʻohana ʻia e ka ʻoihana kiʻi ʻoniʻoni. Hoʻohana ʻia ʻo Samarium ma ke ʻano he catalyst i kekahi mau ʻoihana, me ka dehydrogenation o ka waiʻona ethanol. Hoʻemi ʻia nā Arylsulfonyl chlorides a me nā arylsulfinates e ka hui pū ʻana o ka samarium a me ka titanium(IV) chloride e hana i ka diaryl disulfides. He neutron absorber, dopant no nā kristal laser.
