Wax lagu daro budada birta ah ee birta ah ee Samarium CAS 7440-19-9 High-Entropy Alloys

Samarium waxay u dhacdaa sida adag/foil ama budo cawl leh oo midabkeedu qalin yahay waana ur aan ur lahayn, guban kara, iyo biyo-celin adag. Dhammaan noocyada samariumka waxaa lagu yaqaanaa inay la falgalaan asiidhyada millatariga ah ee siidaaya gaasta hydrogen ee ololaysa/qarxa. Samarium marka la taabto biyaha ayaa ka fal celisa oo ka saartaa gaasaska gubanaya. Samarium kuma habboona asiidh xooggan, walxo oksaydhyo ah oo xooggan, iyo halogens. Codsiga ganacsi ee ugu weyn ee samariumku wuxuu ku jiraa magnets-ka samarium-cobalt. Magnet-yadani waxay leeyihiin hanti magnetization joogto ah. Xeryahooda Samarium ayaa la muujiyay inay u adkeysan karaan heerkul aad u sarreeya, oo ka sarreeya 700 ° C, iyaga oo aan lumin hantidooda magnetka. Isotope-ka shucaaca samarium-153 waa qaybta ugu weyn ee dawada samarium 153Sm lexidronam (Quadramet). Kuwaas waxaa loo isticmaalaa daawaynta kansarrada sambabada, qanjirka 'prostate', iyo naaska iyo osteosarcoma. Samarium waxa kale oo loo isticmaalaa kicinta falcelinta kiimikaad, shukaansi shucaac ah, iyo laysarka raajada. Samarium waxa loo isticmaalaa kicin ahaan dareen-celinta dabiiciga ah qaarkood: Samarium iodide (SmI2) waxa isticmaala farmashiyaal cilmi-baadhiseed oo dabiici ah si ay u sameeyaan noocyada synthetic ee alaabta dabiiciga ah. Samarium waxay ku dhacdaa fiirsashada ilaa 2.8% macdanno dhowr ah oo ay ku jiraan cerite, gadolinite, samarskite, monazite, iyo bastn?site, labada ugu dambeeya waa ilaha ganacsiga ee ugu badan ee curiyaha. Macdantan waxaa inta badan laga helaa Shiinaha, Maraykanka, Brazil, India, Sri Lanka, iyo Australia; Shiinaha ayaa ilaa hadda hormoodka ka ah macdanta iyo wax soo saarka samariumka. Shucaaca isotope samarium-153 waa qaybta ugu weyn ee daroogada samarium (153Sm) lexidronam (Quadramet), kaas oo dila unugyada kansarka ee daaweynta kansarka sanbabada, kansarka qanjirka 'prostate', kansarka naasaha, iyo osteosarcoma. Isotope, samarium-149, waa nuugista neutron xooggan oo sidaas darteed lagu daro ulaha kantaroolka ee reactors nukliyeerka. Samaariya oxide waxa loo isticmaalaa samaynta galaas gaar ah oo infrared-adsorbing ah iyo xudunta kaarboon arc-lamp oxide electrodes iyo sida kicinta fuuq-baxa iyo fuuq-baxa ethanol. Iskudhiskeeda leh kobalt (SmCo5) waxaa loo isticmaalaa samaynta walxo magnet joogto ah oo cusub. Samarium ma laha door bayooloji ah, laakiin waxaa la xusay inay kiciso dheef-shiid kiimikaadka. Cusbada samariumka ah ee milma waa sun yar marka la nuugo, waxaana jira khataro caafimaad kuwaas oo lala xiriiriyo sababtoo ah soo-gaadhista samariumku waxay sababtaa cuncun maqaarka iyo isha. Mid ka mid ah codsiyada ugu muhiimsan ee samariumka ayaa ku jira samarium-cobalt magnets, kuwaas oo leh hal-abuur magac ahaan SmCo5 ama Sm2Co17. Waxay leeyihiin magnetisation sare oo joogto ah, kaas oo qiyaastii 10,000 jeer ka badan birta waana kan labaad ee kaliya ee magnets neodymium. Samarium way fududahay in magnetize, laakiin aad bay u adagtahay in la gooyo. Tani waxay ka dhigeysaa mid ku habboon soo saarista magnets joogto ah (SmCo5) kuwaas oo qayb ka ah saxanadaha adag ee kombuyuutarrada. Samarium sidoo kale waxaa loo isticmaalaa sida nuugista neutron ee reactors nukliyeerka, iyo sidoo kale laysarka iyo cilmi-baarista birta. Waxay ka kooban tahay qiyaastii 1% biraha ku jira birta misch, daawaha ku jira muraayadaha sigaarka. Sidoo kale waa mid ka mid ah dhowr dhul oo naadir ah oo loo isticmaalo nalalka daadka iyo nalalka kaarboon-arc ee ay isticmaalaan warshadaha sawir-qaadista. Samarium waxa loo isticmaalaa kiciyayaal dhawr warshadood ah, oo ay ku jiraan fuuq-baxa khamriga ethanol. Arylsulfonyl chlorides iyo arylsulfinates waxaa la dhimay isku darka samarium iyo titanium (IV) chloride si loo sameeyo diaryl disulfides. Waa nuugeeyaha neutron-ka, oo loo yaqaanno crystals lasers.
