Samarium

Kev piav qhia

Samarium Sm99.9%, 99.99%, asilvery dawb tsis tshua muaj ntiaj teb hlau, nrog triclinic siv lead ua qauv, melting point 1072 ° C thiab ceev 7.54 g / cm³,triclinic siv lead ua qauv, uas yog ruaj khov nyob rau hauv qhuav huab cua tab sis yooj yim rau oxidized nyob rau hauv ntub huab cua thiab ua ke nrog nonmetallic ntsiab, soluble nyob rau hauv acid tab sis insoluble nyob rau hauv dej.Samarium tuaj yeem sib cais los ntawm lwm lub ntiaj teb tsis tshua muaj los ntawm ion pauv txoj kev, lossis npaj los ntawm kev txo cov samarium oxide nrog barium lossis lanthanum.Samarium yuav tsum khaws cia rau hauv qhov chaw txias thiab qhuav, thiab kom deb ntawm oxidants, acids thiab noo noo thiab lwm yam.Samarium yog siv tau zoo li cov khoom siv neutron-absorbing hauv kev lag luam atomic zog, cov khoom siv hlau nplaum ruaj khov, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv microwave thiab infrared, cov ntaub ntawv laser, thiab tseem nrhiav tau daim ntawv thov nyob rau hauv cov khoom hauv lub xeev tivthaiv thiab superconducting technology teb raws li magnetized. yooj yim tab sis nyuaj rau demagnetized, thiab rau hluav taws xob thiab ceramic industries.

Kev xa khoom

Samarium Sm Hlau nrog purity ntawm Sm / RE 99.9%, 99.99% thiab TRE 99.0% ntawm Western Minmetals (SC) Corporation tuaj yeem xa hauv ntau hom hmoov, pob, chunk, granule thiab ingort hauv pob ntawm 1kg lub tshuab nqus tsev sib xyaw txhuas lub hnab nrog thawv thawv sab nraud los yog raws li kev kho mob rau cov tshuaj zoo meej.
