Kufotokozera Kwachidule:

Dzina la Chinthu:

Lanthanum oxide kupanga|CAS1312-81-8 kupereka China|4N5Chiyero Chapamwamba

Mawu ofanana: Lanthanum(III) oxide, Lanthana, Lanthanum trioxide

Nambala ya CAS:1312-81-8

Fomula ya Maselo:La2O3

Kulemera kwa Maselo:325.8

Maonekedwe:Ufa woyera, susungunuka m'madzi koma umasungunuka mu asidi. Ndi wochepa kwambiri, umatha kuyamwa chinyezi ndi mpweya woipa kuchokera mumlengalenga mwachangu ndipo uyenera kusungidwa mu chidebe chotsekedwa.

Mafotokozedwe osinthidwa amapezeka mukapempha.

Kufotokozera & Makhalidwe

Kufotokozera: WNX imagwiritsa ntchito ukadaulo wapamwamba wopanga zinthu ndipo imagwiritsa ntchito zipangizo zapamwamba kwambiri kuti ipange zinthu zapamwamba kwambiriLanthanum oxide.

Zinthu Zofunika Kwambiri:

Kuyera Kwambiri:Lanthanum oxide Mulibe zodetsa zochokera ku zinthu zosoŵa zapadziko lapansi (monga chitsulo, calcium, sodium), ndipo kuchuluka kwa zodetsazo n'kochepa.

Kusungunuka Kwabwino:Lanthanum oxide imatha kusungunuka mofulumira m'madzi ndi m'ma asidi amphamvu.

Kusasinthasintha: Kuyang'anira bwino kwambiri kupanga zinthuLanthanum oxide kuonetsetsa kuti zinthu zopangidwa m'mafakitale akuluakulu zikhale zabwino komanso zokhazikika.

Magalasi ndi zoumba: Lanthanum oxide ndiye chinthu chofunikira kwambiri popanga magalasi olondola a kuwala ndi ulusi wowala, zomwe zimapangitsa kuti galasi likhale ndi mphamvu zowala komanso mphamvu zofalikira. Imagwiritsidwa ntchito kwambiri popanga magalasi apamwamba a makamera ndi ma microscope. Pankhani ya zoumba zamagetsi zamagetsi, imagwiritsidwa ntchito ngati chowonjezera popanga ma capacitor a ceramic ndi zoumba za piezoelectric kuti ziwongolere mphamvu zamagetsi komanso kukhazikika kwa kutentha kwa zinthuzo.

Chothandizira: Mu makampani opanga mafuta, lanthanum oxide imagwiritsidwa ntchito ngati gawo lofunikira la ma catalyst a catalytic cracking (FCC), zomwe zimathandiza kuwonjezera kutulutsa ndi ubwino wa mafuta. Ikhozanso kugwira ntchito ngati chothandizira pazochitika zinazake za mankhwala, monga oxidation ya carbon monoxide ndi momwe methane oxidation imagwirira ntchito popanga ethane ndi ethylene.

Zipangizo zogwirira ntchito: Lanthanum oxide ndi chinthu chopangira lanthanum boride (LaB)₆), chomwe ndi chinthu chabwino kwambiri chotulutsa mpweya wa thermoelectronic. Lanthanum oxide imagwiranso ntchito zofunika kwambiri m'magawo monga zinthu zosungiramo haidrojeni ndi ma cell amafuta. Mwachitsanzo, ma alloy a lanthanum-nickel angagwiritsidwe ntchito posungira haidrojeni.
