Cerium oxide ndi chinthu chamafuta omwe ali ndi mawonekedwe a mankhwala Ceo2, chikasu chachikaso kapena chikasu chofiirira. Kuchulukitsa 7.13g / masentimita, kusungunuka kwa 2397 ° C, zopanda mphamvu m'madzi ndi alkali, sungunuka pang'ono mu asidi. Kutentha kwa 2000 ° C ndi kukakamizidwa kwa ma 15mm, haidrogen atha kugwiritsidwa ntchito pochepetsa ceum oxide kuti apeze cerium oxide. Kutentha kumakhala kwaulere pa 2000 ° C ndi kukakamizidwa kuli kwaulere ku 5MPA, cerium oxide ndi chikasu chachikasu chofiirira, ndi pinki. Amagwiritsidwa ntchito ngati zokumba, chothandizira, chonyamula katundu (Othandizira), Mafuta a Mafuta a Slallrolyte, magalimoto amagetsi amatulutsa, enramics yamagetsi, etc.
Chidziwitso Chachitetezo
Mchere waCerium OxideZinthu zamtundu wina zimatha kuchepetsa zomwe prothrombin, zimalepheretsa, zimaletsa mibadwo ya thrombin, yopatsira mitu ya phosphoogen mankhwala. Kuzizwitsa kwa zinthu zam'mlengalenga kumachepa ndi kuwonjezeka kwa kulemera kwa atomiki.
Kupumira kwa dothi lokhala ndi miyala yamtengo wapatali kumatha kuyambitsa pneumconosis, ndipo chloride yake imatha kuwononga khungu ndikukhumudwitsa mucous nembanemba wamaso.
Cholinga chovomerezeka: Cerium oxide 5 mg / m3, cerium hydroxide 5 mg hydroxide 5 mg hydroxide ngati pali wailesiya, ndipo fumbi liyenera kuletsedwa kufalikira.
makhalidwe
Choyipa choyera ndi choyera choyera kapena chikasu cha crystal, ndipo chopukusa chimakhala chikasu kapena chofiirira kuti chikafinya chofiirira (chifukwa chimakhala ndi lanthanum, Praseodyoymium, etc.). Pafupifupi insuluble m'madzi ndi asidi. Kuchulukitsa 73. Malo osungunuka: 1950 ° C, owotcha: 3500 ° C. Poizoni, mlingo wa Median kupha (rat, pakamwa) ndi pafupifupi 1g / kg.

Index yabwino
Ogawidwa ndi Kuyera: Kuyera Kosatsika: Zoyera Zoposa 99%, Zoyera Zokwera: 99.9% ~ 99.99%, kuyera kwapamwamba kwambiri kuposa 99.999%
Ogawidwa ndi kukula kwa tinthu: ufa wopaka, micron, submicron, nano
Malangizo a Chitetezo: Chogulitsacho ndi chakupha, osakhumudwitsa, osakwiya, otetezeka komanso odalirika, ndipo samachita ndi madzi ndi zinthu zachilengedwe. Ndiwofotokozera wamkulu wagalasi kwambiri, kungopanga wothandizira ndi mankhwala ochitira mankhwala.
gwilitsa nchito
ockizing wothandizira. Chothandizira pakusintha kwa organic. Kusanthula kwachitsulo ndi chitsulo chachitsulo monga chitsulo chambiri chambiri. Kusanthula kwatsopano kwa Redox. Galasi lopanga. Mafuta a Ogarifier. Kutentha kopitilira muyeso.
Ntchito ngati zowonjezera mu malonda agalasi, monga chopukusira chagalasi, komanso monga anti-anti-ultraviolet zotsatira zodzikongoletsera. Yakulitsidwa mpaka pogaya galasi, mandala owala, ndipo amasewera maudindo a decolorization, kumveketsa, komanso mayamwidwe a elpraviolet agalasi.
