Qhov cuam tshuam ntawm cerium ntawm lub cev feem ntau cuam tshuam nrog Hepatotoxicity thiab Osteotoxicity thiab Esteotoxicity, nrog rau cov kev cuam tshuam zoo rau ntawm qhov muag lub paj hlwb. Cerium and its compounds are detrimental to the human epidermis and optic nervous system, with even minimal inhalation posing a risk of disability or life-threatening conditions. C cerium ox oxide yog tshuaj lom rau tib neeg lub cev, ua rau mob siab rau daim siab thiab pob txha. Hauv lub neej txhua hnub, nws yog qhov tseem ceeb los ua kev ceev faj thiab zam kom tsis txhob nqus tau cov tshuaj lom neeg.
Tshwj xeeb, cerium oxide tuaj yeem txo cov ntsiab lus prothrosidomic rendering nws tsis ua haujlwm; inhibit thrombin tiam; precipion fibrinogen; thiab ua kom pom tseeb hais tias muaj kev sib cav sib ceg. Ntev ntev li cov khoom siv nrog cov ntsiab lus tsis tshua muaj cov ntsiab lus tsis tshua muaj peev xwm tiv thaiv cov ntsiab lus hepatic thiab pob txha hepatoral.
Tsis tas li ntawd, cov hmoov polishing muaj creium oxide lossis lwm yam tshuaj yuav ncaj qha rau lub ntsws ua pa ua pa tau ua rau lub ntsws ua haujlwm ua kom muaj peev xwm ua kom cov tawv nqaij. Txawm hais tias cerium partolive cerium muaj qhov tsawg tshaj plaws nqus tus nqi hauv lub cev, cov menyuam mos muaj qhov sib xyaw ntawm 144ce kev nqus hauv lawv txoj hnyuv. Cov xov tooj cua cerium feem ntau sib thooj hauv daim siab thiab pob txha nyob rau lub sijhawm.
5. YogCerium carbonateSoluble hauv dej?
Cerium carbonate yog insoluble hauv dej tab sis soluble hauv acidic daws. Nws yog ib qho chaw ruaj khov uas tsis hloov thaum raug huab cua tab sis hloov dub nyob rau hauv lub teeb ultraviolet.
6.Cov cerium nyuaj lossis muag?
Cerium yog qhov muag muag, silvery-dawb hauv ntiaj teb hlau nrog cov tshuaj lom neeg muaj kuab lom thiab cov tshuaj malletse uas tuaj yeem txiav nrog rab riam.
Lub zog ntawm cerium kuj txhawb nws qhov muag muag. Cerium muaj lub ntsiab lus melting ntawm 795 ° C, ib lub qhov cub npau npau ntawm 3443 ° C, thiab ntom ntawm 6.67 g / ml. Tsis tas li ntawd, nws cov xim tsis muaj xim hloov thaum raug huab cua. Cov khoom no qhia tau tias cerium yog qhov tseeb yog qhov muag thiab du ntau hlau.
7. Can cerium oxidise dej?
Cerium muaj peev xwm ntawm oxidizing dej vim nws cov tshuaj xws li. Nws nthuav tawm maj mam nrog dej txias thiab sai nrog dej kub, ua rau muaj kev tsim ntawm cerium hydroxide thiab hydrogen roj. Tus nqi ntawm cov tshuaj tiv thaiv no nce hauv dej kub piv rau dej txias.
8. Puas yog cerium tsawg?
Yog lawm, cerium yog suav tias yog ib qho kev tsis tshua muaj qhov tshwm sim li ntawm 0.0046% ntawm lub ntiaj teb kev ua kaub puab, ua rau nws muaj ib qho ntau tshaj plaws ntawm lub ntiaj teb tsis tshua muaj neeg nyob hauv ntiaj teb tsawg.
9. Puas yog cerium ib qho kua roj lossis roj?
CORIUMs muaj raws li cov khoom ntawm chav sov thiab cov xwm txheej siab. Nws zoo li yog cov nyiaj-grey npaum li cas cov hlau uas muaj cov qauv sib txawv thiab softer dua li hlau. Txawm hais tias nws tuaj yeem hloov mus rau hauv cov kua nyob rau hauv cov cua kub, ntawm cov xwm txheej zoo li qub tau vim yog 795 ° C thiab boiling taw tes ntawm 3443 ° C.
10. Dab tsi yog qhov zoo li?
Cerium nthuav tawm cov tsos ntawm cov nyiaj-grey reassers hlau yog pab pawg ntawm kev tsis tshua muaj ntiaj teb (rees). Nws lub cim tshuaj lom neeg yog CE thaum nws atomic naj npawb yog 58. Nws tuav lub rees. Nws ua haujlwm ua tus neeg sawv cev txo zoo tshaj plaws feem ntau siv rau kev tsim tawm tag nrho.
Lub zog lub cev muaj xws li: ntom ntawj xws li ntawm 6.7-6.9 nyob ntawm cov qauv siv lead ua; Melting taw tes sawv ntawm 799 ℃ thaum thaum lub sij hawm npau npau txog3426 ℃. Lub npe "Ceeline" pib los ntawm cov lus Askiv ", uas yog hais txog kev xav tsis thoob. Cov ntsiab lus feem pua nyob rau hauv lub ntiaj teb tus nqi them rau kwv yees li ntawm0.0046%, rov qab ua nws tau yooj yim ntawm cov rees.
Ceriu feem ntau tshwm sim hauv monazite, Bastnaesite, thiab cov khoom siv thiab cov khoom thiab cov khoom siv hluav taws xob hauv uralanium. Hauv kev lag luam, nws pom dav cov ntawv thov xws li alloy manufacturing kev siv nyiaj.
