Samarium zitsulo | Sm cube | CAS 7440-19-9 | Zosowa zapadziko lapansi

Kufotokozera Kwachidule:

Samarium imagwiritsidwa ntchito popanga makristalo a calcium chloride kuti agwiritsidwe ntchito mu lasers optical. Amagwiritsidwanso ntchito pagalasi loyamwitsa la infrared komanso ngati chotengera nyutroni mu zida zanyukiliya.

Titha kupereka chiyero chachikulu 99.9%.

Samarium ndi chinthu chosowa padziko lapansi chomwe ndi chitsulo choyera-choyera, chofewa, ndi ductile. Ili ndi malo osungunuka a 1074 °C (1976 °F) ndi malo otentha a 1794 °C (3263 °F). Samarium imadziwika kuti imatha kuyamwa ma neutroni ndikugwiritsa ntchito popanga maginito a samarium-cobalt, omwe amagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikiza ma mota ndi ma jenereta.
Chitsulo cha Samarium chimapangidwa kudzera m'njira zosiyanasiyana, kuphatikizapo electrolysis ndi kuchepetsa kutentha. Amagulitsidwa ngati ma ingots, ndodo, mapepala, kapena ufa, ndipo amathanso kupangidwa m'njira zina kudzera munjira monga kuponyera kapena kufota.
Chitsulo cha Samarium chili ndi zinthu zingapo zomwe zingagwiritsidwe ntchito, kuphatikizapo kupanga zopangira, ma alloys, ndi zamagetsi, komanso kupanga maginito ndi zipangizo zina zapadera. Amagwiritsidwanso ntchito popanga mafuta a nyukiliya komanso kupanga magalasi apadera ndi zoumba.

Kugwiritsa ntchito

Maginito Okhazikika: Chimodzi mwazinthu zofunika kwambiri za samarium ndikupanga maginito a samarium cobalt (SmCo). Maginito okhazikikawa amadziwika chifukwa champhamvu zawo zamaginito komanso kukhazikika kwamafuta, zomwe zimawapangitsa kukhala abwino kugwiritsidwa ntchito pamapulogalamu apamwamba kwambiri monga ma mota, ma jenereta, ndi masensa. Maginito a SmCo ndi ofunika kwambiri m'mafakitale oyendetsa ndege ndi chitetezo, kumene kudalirika ndi ntchito ndizofunikira kwambiri.
Zida Zanyukiliya: Samarium imagwiritsidwa ntchito ngati chotengera cha nyutroni mu zida zanyukiliya. Imatha kugwira ma neutroni, motero imathandizira kuwongolera njira ya fission ndikusunga kukhazikika kwa riyakitala. Samarium nthawi zambiri imaphatikizidwa muzitsulo zowongolera ndi zigawo zina, zomwe zimathandiza kuti pakhale ntchito yotetezeka komanso yogwira ntchito yamagetsi a nyukiliya.
Phosphor ndi Kuwala: Mankhwala a Samarium amagwiritsidwa ntchito mu phosphors pakuwunikira ntchito, makamaka machubu a cathode ray (CRTs) ndi nyali za fulorosenti. Zida za Samarium-doped zimatha kutulutsa kuwala pamafunde enaake, potero kumapangitsa kuti mtundu ukhale wabwino komanso magwiridwe antchito amagetsi. Ntchitoyi ndiyofunikira pakupanga matekinoloje apamwamba owonetsera komanso njira zowunikira zowunikira mphamvu.
Alloying wothandizira: Samarium yoyera imagwiritsidwa ntchito ngati alloying alloy muzitsulo zosiyanasiyana zazitsulo, makamaka popanga maginito osowa padziko lapansi ndi zipangizo zina zogwira ntchito kwambiri. Kuphatikizika kwa samarium kumapangitsa kuti makinawo azigwira bwino ntchito komanso kukana dzimbiri kwa ma alloy awa, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito m'mafakitale amagetsi, zamagalimoto ndi zakuthambo.
