I-Rare Earth powder metallurgy additing I-Samarium powder yensimbi CAS 7440-19-9 High-Entropy Alloys

I-Samarium yenzeka njengokuqinile/amafoyili anombala osiliva noma impushana empunga futhi iqinile, enganuki, evutha umlilo, futhi esebenza emanzini. Zonke izinhlobo ze-samarium zaziwa ngokusabela ngama-asidi acwebileyo akhipha igesi ye-hydrogen evuthayo/eqhumayo. I-Samarium lapho ithintana namanzi iyasabela futhi ikhulule amagesi avuthayo kakhulu. I-Samarium ayihambisani nama-asidi aqinile, ama-oxidizing agents aqinile, nama-halogen. Ukusetshenziswa okukhulu kwezohwebo kwe-samarium kukumagnethi we-samarium-cobalt. Lezi zibuthe zinempahla yamagnetisation engapheli. Amakhemikhali e-Samarium aboniswe ukuthi amelana namazinga okushisa aphakeme kakhulu, ngaphezu kuka-700 ° C, ngaphandle kokulahlekelwa izakhiwo zawo kazibuthe. I-radioactive isotope samarium-153 iyingxenye enkulu yesidakamizwa i-samarium 153Sm lexidronam (Quadramet). Lezi zisetshenziswa ekwelapheni umdlavuza wamaphaphu, i-prostate, nebele kanye ne-osteosarcoma. I-Samarium iphinde isetshenziswe ku-catalysis of chemical reactions, dating radioactive, kanye ne-x-ray laser. I-Samarium isetshenziswa njenge-catalyst ekuphenduleni okuthile kwe-organic: I-Samarium iodide (SmI2) isetshenziswa osokhemisi bocwaningo lwe-organic ukwenza izinguqulo zokwenziwa zemikhiqizo yemvelo. I-Samarium yenzeka ngokugxila okungafika ku-2.8% kumaminerali amaningana afaka i-cerite, i-gadolinite, i-samarskite, i-monazite, ne-bastn?site, okokugcina okubili okuyimithombo evamile yokuhweba ye-elementi. La maminerali atholakala kakhulu eChina, e-United States, eBrazil, e-India, eSri Lanka nase-Australia; I-China ihamba phambili emhlabeni wonke kwezokumbiwa phansi nokukhiqizwa kwe-samarium. I-Radioactive isotope samarium-153 iyingxenye enkulu yesidakamizwa i-samarium (153Sm) i-lexidronam (Quadramet), ebulala amangqamuzana omdlavuza ekwelapheni umdlavuza wamaphaphu, umdlavuza wendlala yesinye, umdlavuza webele, kanye ne-osteosarcoma. I-isotope, i-samarium-149, iyisithako esinamandla se-neutron ngakho-ke yengezwa ezintini zokulawula zama-reactors enyukliya. I-Samariya oxide isetshenziselwa ukwenza ingilazi ekhethekile ye-infrared-adsorbing kanye nama-cores we-carbon arc-lamp oxide electrode futhi njenge-catalyst yokuphelelwa amanzi emzimbeni kanye ne-dehydrogenation ye-ethanol. Inhlanganisela yayo ne-cobalt (SmCo5) isetshenziswa ekwenzeni into entsha kazibuthe unomphela. I-Samarium ayinayo indima yezinto eziphilayo, kodwa kuye kwaphawulwa ukuthi ivuselela umzimba. Usawoti we-samarium oncibilikayo unobuthi obuncane ngokumunca, futhi kunezingozi zezempilo ezihlobene nalezi ngoba ukuchayeka ku-samarium kubangela ukucasuka kwesikhumba namehlo. Enye yezinhlelo ezibaluleke kakhulu ze-samarium ikumazibuthe we-samarium–cobalt, anokwakheka okuzisholo kwe-SmCo5 noma i-Sm2Co17. Anamandla kazibuthe aphezulu unomphela, okungama-iron izikhathi ezingaba ngu-10,000 futhi angokwesibili ngemva kwamagnetic we-neodymium. I-Samarium kulula ukwenza i-magnetize, kodwa kunzima kakhulu ukuyikhipha. Lokhu kuyenza ilungele ukwakhiwa kwezibuthe ezihlala njalo (i-SmCo5) eziyingxenye yama-hard disks amakhompyutha.I-Samarium iphinde isetshenziswe njengesimunyisi neutron kuma-reactors enuzi, kanye namalaser kanye nocwaningo lwe-metallurgical. Yakha cishe u-1% wezinsimbi ku-misch metal, ingxubevange kumafilantshi kagwayi. Futhi ingenye yezindawo ezimbalwa ezingavamile ezisetshenziswa kumalambu esikhukhula kanye namalambu e-carbon-arc asetshenziswa imboni yezithombe ezinyakazayo. I-Samarium isetshenziswa njenge-catalyst ezimbonini eziningana, kuhlanganise ne-dehydrogenation ye-ethanol alcohol. I-Arylsulfonyl chlorides nama-arylsulfinates ancishiswa ngenhlanganisela ye-samarium ne-titanium(IV) chloride ukwenza i-diaryl disulfides. Kuyi-neutron absorber, i-dopant yamakristalu e-laser.
