Rare pasi poda metallurgy additive Samarium simbi hupfu CAS 7440-19-9 High-Entropy Alloys

Samarium inoitika sesirivheri-ruvara rakasimba/mafoils kana grey poda uye isinganhuhwi, inobvira, uye inogadzirisa mvura yakasimba. Mhando dzese dzesamarium dzinozivikanwa kuita ne dilute acids inoburitsa inopfuta / inoputika hydrogen gasi. Samarium pakubata nemvura inobata uye inosunungura magasi anopisa zvakanyanya. Samarium haienderani neakasimba acids, yakasimba oxidising agents, uye halogens. Iyo huru yekutengesa kushandiswa kwesamarium iri musamarium-cobalt magineti. Aya magineti ane chisingaperi magnetisation pfuma. Mishonga yeSamarium yakaratidzwa kuti inomira zvakanyanya kutonhora, pamusoro pe700 ° C, pasina kurasikirwa nemagineti. Iyo radioactive isotope samarium-153 ndicho chikamu chikuru chemushonga samarium 153Sm lexidronam (Quadramet). Aya anoshandiswa mukurapa kenza dzemapapu, prostate, uye zamu uye osteosarcoma. Samarium inoshandiswawo mu catalysis yemakemikari reactions, radioactive dating, uye mu x-ray laser. Samarium inoshandiswa sechinhu chinokonzeresa mune zvimwe organic reactions: Samarium iodide (SmI2) inoshandiswa ne organic research chemist kugadzira shanduro dzekugadzira dzezvigadzirwa zvechisikigo. Samarium inoitika nekuisa pfungwa kusvika 2.8% mumaminerari akati wandei anosanganisira cerite, gadolinite, samarskite, monazite, uye bastn?saiti, maviri ekupedzisira ari anonyanya kuzivikanwa ekutengesa echinhu. Zvicherwa izvi zvinonyanya kuwanikwa kuChina, United States, Brazil, India, Sri Lanka, neAustralia; China ndiyo inotungamira pasi rose mumigodhi yesamarium nekugadzira. Radioactive isotope samarium-153 ndicho chikamu chikuru chemushonga samarium (153Sm) lexidronam (Quadramet), inouraya maseru egomarara mukurapa cancer yemapapu, kenza yeprostate, kenza yemazamu, uye osteosarcoma. Iyo isotopu, samarium-149, isimba rakasimba renyutroni uye saka rinowedzerwa kune tsvimbo dzekudzora dzenyukireya reactor. Samaria oxide inoshandiswa kugadzira yakakosha infrared-adsorbing girazi uye macores ecarbon arc-lamp oxide electrodes uye sechinhu chinokonzeresa kupera kwemvura uye dehydrogenation ethanol. Mushonga wayo une cobalt (SmCo5) unoshandiswa kugadzira chinhu chitsva chegineti. Samarium haina basa rehupenyu, asi yakacherechedzwa kuti inokurudzira metabolism. Soluble samarium salt ine chepfu zvinyoro nekupinza, uye kune njodzi dzehutano dzakabatanidzwa neizvi nekuti kuratidzwa kune samarium kunokonzera ganda uye kutsamwa kweziso. Imwe yeanonyanya kukosha mashandisirwo esamarium iri musamarium-cobalt magineti, ane zita rekuti SmCo5 kana Sm2Co17. Vane magineti echigarire akakwirira, ayo anoita kanokwana ka10 000 kupfuura esimbi uye ari wechipiri chete kune aya emagetsi eneodymium. Samarium iri nyore kuita magineti, asi yakaoma kwazvo kuita demagnetize. Izvi zvinoita kuti ive yakanakira kugadzirwa kwemagineti echigarire (SmCo5) ari chikamu chemadhisiki akaoma emakombuta. Samarium inoshandiswawo senyuturoni inonwisa munyukireya reactor, pamwe chete nelaser uye metallurgical research. Inogadzira inenge 1% yesimbi mumisch simbi, alloy mufodya refodya. Iyo zvakare imwe yeakawanda isingawanzo-yepasi anoshandiswa mumafashama maraiti uye kabhoni-arc marambi anoshandiswa neiyo inofamba mifananidzo indasitiri. Samarium inoshandiswa sechinhu chinokonzeresa mumaindasitiri akati wandei, kusanganisira dehydrogenation ye ethanol doro. Arylsulfonyl chlorides uye arylsulfinates zvinoderedzwa nemusanganiswa wesamarium uye titanium(IV) chloride kugadzira diaryl disulfides. Iyo neutron absorber, dopant yelaser makristasi.
