Kev cai hlau Europium (Eu) Cov ntaub ntawv

Europium (Eu) Cov ntaub ntawv dav dav:

Europium, molecular mis: Eu; molecular hnyav: 151.964, silvery dawb, tuaj yeem hlawv rau hauv oxide; oxide yog kwv yees li dawb. Europium yog hlau-grey hlau nrog lub melting point ntawm 822 ° C, boiling point ntawm 1597 ° C, thiab ib tug ceev ntawm 5.2434g / ㎝³; nws yog qhov softest thiab volatile feem ntau ntawm cov khoom tsis tshua muaj hauv ntiaj teb. Europium yog cov hlau nquag tshaj plaws ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb: nyob rau hauv chav tsev kub, europium tam sim ntawd poob nws cov xim hlau nyob hauv huab cua thiab oxidized sai sai rau hauv cov hmoov; nws reacts hnyav nrog dej txias los tsim hydrogen; europium tuaj yeem cuam tshuam nrog boron, carbon, sulfur, phosphorus, hydrogen, thiab nitrogen Tos rau cov tshuaj tiv thaiv.

Eu-3N-COA

Europium yog dav siv nyob rau hauv kev tsim cov reactor tswj cov ntaub ntawv thiab neutron shielding cov ntaub ntawv. Nws yog siv los ua phosphor rau xim TV teeb thiab muaj cov ntawv thov tseem ceeb hauv europium (Eu) cov ntaub ntawv laser thiab kev lag luam atomic zog. Europium oxide kuj tuaj yeem siv los ua cov xim lo ntsiab muag thiab cov ntxaij lim dej rau cov khoom siv sib nqus npuas.

Europium (Eu) Hlau Element Txheej txheem cej luam:

Peb smelts ib yam ntawm cov hlau thiab feem ntau lwm cov ntaub ntawv siab heev rau hauv pas nrig, bar los yog phaj daim ntawv, los yog cov neeg muas zaub muab cov khoom kos duab.

Peb muag cov khoom sib txawv ntawm cov khoom siv hlau los ntawm cov khoom hnyav los yog cov khoom siv sib txawv hauv cheeb tsam tshawb fawb thiab rau cov cuab yeej tshiab.

Piv txwv li: Europium sputtering phiaj, Europium pob, Europium ingot, Europium pellets, Europium lub voos xwmfab. Lwm cov duab muaj nyob ntawm kev thov.
