Incazelo emfushane:

Igama Lomkhiqizo:

I-Lanthanum Oxide ukukhiqiza|i-CAS1312-81-8 ukunikeza iShayina|4N5Ukuhlanzeka Okuphezulu

Amagama afanayo: I-Lanthanum(III) oxide, i-Lanthana, i-Lanthanum trioxide

Inombolo ye-CAS:1312-81-8

Ifomula Yamamolekyuli:La2O3

Isisindo sama-molecule:325.8

Ukubukeka:Impuphu emhlophe, ayincibiliki emanzini kodwa incibilika ku-asidi. Njengoba i-hygroscopic kakhulu, ingamunca umswakama kanye ne-carbon dioxide emoyeni ngokushesha futhi kufanele igcinwe esitsheni esivaliwe.

Incazelo kanye nezici

Incazelo: I-WNX isebenzisa ubuchwepheshe bokukhiqiza obuthuthukisiwe obuzenzakalelayo futhi isebenzisa izinto zokusetshenziswa ezisezingeni eliphezulu ukukhiqiza ikhwalithi ephezuluI-Lanthanum Oxide.

Izici Eziyinhloko:

Ubumsulwa Obuphezulu:I-Lanthanum Oxide ayinakho ukungcola okuvela ezintweni ezingavamile zomhlaba (njenge-iron, i-calcium, i-sodium), futhi okuqukethwe kokungcola kuphansi.

Ukuncibilika Okuhle:I-Lanthanum Oxide ingancibilika ngokushesha emanzini kanye nama-asidi aqinile.

Ukuvumelana: Ukuphathwa kweqoqo okuqinile ekukhiqizweni kweI-Lanthanum Oxide kuqinisekisa ikhwalithi ezinzile yokukhiqiza okukhulu kwezimboni.

Ingilazi yokukhanya kanye ne-ceramics: I-Lanthanum oxide iyinto eyinhloko yokukhiqiza ingilazi yokukhanya enembile kanye ne-fibers yokukhanya, okuthuthukisa kakhulu inkomba yokukhanya kanye nezakhiwo zokusabalala kwengilazi. Isetshenziswa kabanzi ekukhiqizweni kwamalensi okukhanya athuthukisiwe amakhamera nama-microscopes. Emkhakheni we-ceramics kagesi, isetshenziswa njengesithasiselo sokwenza ama-capacitor e-ceramic kanye ne-ceramics ye-piezoelectric ukuthuthukisa izakhiwo zikagesi kanye nokuzinza kwezinga lokushisa kwezinto.

I-Catalyst: Embonini ye-petrochemical, i-lanthanum oxide isetshenziswa njengengxenye ebalulekile ye-catalysts ye-catalytic cracking (FCC), esiza ukwandisa umkhiqizo kanye nekhwalithi kaphethiloli. Ingasebenza futhi njenge-catalyst yezimpendulo ezithile zamakhemikhali, njengokushiswa kwe-carbon monoxide kanye nokusabela kwe-methane oxidation ukwakha i-ethane ne-ethylene.

Izinto ezisebenzayo: I-Lanthanum oxide iyinto eluhlaza yokulungiselela i-lanthanum boride (LaB)₆), okuyinto enhle kakhulu ye-thermoelectronic emission cathode. I-Lanthanum oxide nayo inezicelo ezibalulekile emikhakheni efana nezinto zokugcina i-hydrogen kanye nama-fuel cell. Isibonelo, ama-lanthanum-nickel alloys angasetshenziswa ukugcina i-hydrogen.
