    Daim ntawv thov

    Tuam Tshoj Samariumium oxide, kuj hu ua Xamali, tseem muaj qhov muaj peev xwm nqus tau zoo, Samarium oxides tau tshwj xeeb hauv cov iav, lasers, thiab cov khoom siv thermoelectric.

    Calcium chloride crystals muaj cov muaju kho nrog Samarium tau ua haujlwm hauv cov kab teeb uas ua rau cov kab teeb pom kev zoo txaus los hlawv cov hlau lossis tsoo lub hli.

    Samarium oxide siv rau hauv qhov muag thiab infrared nqus lub khob kom nqus tau hluav taws xob infrism. Tsis tas li, nws yog siv los ua neutron marorober hauv kev tswj pas nrig rau cov hwj huam nuclear.

    Cov oxide catalyzes lub cev qhuav dej ntawm cov dej cawv uas muaj duab uas muaj duab uas muaj duab uas muaj hnub nyoog muaj hnub nyoog muaj qoob loo aldehydes thiab ketones.
