Rare ƙasa foda karafa ƙari Samarium karfe foda CAS 7440-19-9 High-Entropy Alloys

Samarium yana faruwa a matsayin mai kauri/foils ko launin toka mai launin azurfa kuma ba shi da wari, mai ƙonewa, da ƙarfi mai ɗaukar ruwa. An san kowane nau'i na samarium don amsawa tare da dilute acid yana fitar da iskar hydrogen mai flammable/ fashewa. Samarium akan hulɗa da ruwa yana amsawa kuma yana 'yantar da iskar gas mai ƙonewa. Samarium bai dace ba tare da acid mai ƙarfi, ma'auni mai ƙarfi mai ƙarfi, da halogens. Babban aikace-aikacen kasuwanci na samarium yana cikin samarium-cobalt maganadiso. Wadannan maganadiso sun mallaki kaddarorin maganadisu na dindindin. An nuna mahadi na Samarium don jure yanayin zafi mai girma, sama da 700 ° C, ba tare da rasa abubuwan da suka dace ba. Samarium-153 isotope na rediyoaktif shine babban bangaren samarium 153Sm lexidronam (Quadramet). Ana amfani da waɗannan a cikin maganin cututtukan daji na huhu, prostate, da nono da osteosarcoma. Hakanan ana amfani da Samarium a cikin haɓaka halayen halayen sinadarai, saduwar rediyo, da laser x-ray. Ana amfani da Samarium azaman mai kara kuzari a cikin wasu halayen halitta: Samarium iodide (SmI2) masanan binciken kwayoyin halitta suna amfani da su don yin nau'ikan samfuran halitta. Samarium yana faruwa tare da maida hankali har zuwa 2.8% a cikin ma'adanai da yawa da suka haɗa da cerite, gadolinite, samarskite, monazite, da bastn?site, na ƙarshe biyu sune tushen kasuwancin gama gari na kashi. Wadannan ma'adanai galibi ana samun su a China, Amurka, Brazil, Indiya, Sri Lanka, da Ostiraliya; Ya zuwa yanzu kasar Sin ce kan gaba a fannin hakar ma'adinai da samarium a duniya. Samarium-153 isotope na rediyoaktif shine babban bangaren samarium (153Sm) lexidronam (Quadramet), wanda ke kashe kwayoyin cutar kansa a cikin maganin ciwon huhu, ciwon prostate, ciwon nono, da osteosarcoma. Isotope, samarium-149, mai ƙarfi ne mai ɗaukar neutron kuma don haka an ƙara shi cikin sandunan sarrafa na'urorin nukiliya. Ana amfani da oxide na Samariya don kera gilashin infrared-adsorbing na musamman da muryoyin lantarki na carbon arc-lamp oxide da kuma azaman mai kara kuzari ga bushewa da bushewar ethanol. Ana amfani da filinsa tare da cobalt (SmCo5) wajen yin sabon abu na maganadisu na dindindin. Samarium ba shi da rawar nazarin halittu, amma an lura da shi don haɓaka metabolism. Gishirin samarium mai narkewa yana da ɗanɗano mai guba ta hanyar sha, kuma akwai haɗarin lafiya da ke tattare da waɗannan saboda kamuwa da samarium yana haifar da kumburin fata da ido. Ɗaya daga cikin mahimman aikace-aikacen samarium yana cikin samarium-cobalt magnets, waɗanda ke da nau'i na SmCo5 ko Sm2Co17. Suna da babban magnetization na dindindin, wanda shine kusan sau 10,000 na baƙin ƙarfe kuma shine na biyu kawai na neodymium maganadiso. Samarium yana da sauƙin maganadisu, amma yana da wahala sosai don ragewa. Wannan ya sa shi manufa forthe kera na dindindin maganadiso (SmCo5) da suke wani ɓangare na wuya faifai don computers.Samarium kuma ana amfani da a matsayin neutron absorber a nukiliya reactors, kazalika da Laser da karfe bincike. Yana da kusan kashi 1% na karafa a cikin misch karfe, gami a cikin fitattun fitattun sigari. Hakanan yana ɗaya daga cikin ƙasashe da ba kasafai da yawa da ake amfani da su a cikin fitilun ambaliya da fitilun carbon-arc waɗanda masana'antar hoton motsi ke amfani da ita. Ana amfani da Samarium azaman mai kara kuzari a masana'antu da yawa, gami da dehydrogenation na barasa ethanol. Arylsulfonyl chlorides da arylsulfinates an rage su ta hanyar haɗin samarium da titanium (IV) chloride don yin diaryl disulfides. Neutron absorber ne, dopant don lu'ulu'u na Laser.
