Fa'amatalaga ma Vaega

Fa'amatalaga: E fa'aaogaina e le WNX tekinolosi gaosiga otometi fa'apitoa ma fa'aaoga mea mata e maualuga le tulaga lelei e gaosia ai mea e sili ona lelei.Lanthanum Oxide.

Vaega Autū:

Mama Maualuga:Lanthanum Oxide e leai ni mea leaga mai elemene seasea o le eleele (e pei o le u'amea, calcium, sodium), ma e maualalo fo'i le aofa'i o mea leaga.

Lelei le sologa lelei:Lanthanum Oxide e mafai ona vave liu suavai i le vai ma ni 'asita malolosi.

Tumau: O le pulega fa'apitoa o le gaosiga oLanthanum Oxide faʻamautinoa le mautu o le tulaga lelei mo le gaosiga tele o alamanuia.

Tioata opitika ma keramika: O le Lanthanum oxide o le mea autū lea mo le gaosia o tioata opitika sa'o ma alava opitika, e fa'aleleia atili ai le fa'asinomaga o le fa'ata'ita'iga ma meatotino fa'asalalau o le tioata. E fa'aaogaina lautele i le gaosiga o tioata opitika fa'aonaponei mo meapueata ma microscopes. I le matata o keramika eletise, e fa'aaogaina o se mea fa'aopoopo i le gaosia o capacitors seramika ma keramika piezoelectric e fa'aleleia atili ai meatotino eletise ma le mautu o le vevela o meafaitino.

Mea Fa'aola: I le alamanuia o petrochemical, o le lanthanum oxide e fa'aaogaina o se vaega taua o mea fa'aola catalytic cracking (FCC), lea e fesoasoani e fa'aleleia atili ai le gaosiga ma le lelei o le penisini. E mafai fo'i ona avea o se mea fa'aola mo ni fa'alavelave fa'akemikolo fa'apitoa, e pei o le fa'aola o le carbon monoxide ma le fa'alavelave o le fa'aola o le methane e fausia ai le ethane ma le ethylene.

Meafaitino aoga: O le Lanthanum oxide o le mea mata lea mo le sauniaina o le lanthanum boride (LaB₆), o se mea sili ona lelei e fa'asalalau ai le thermoelectronic emission cathode. O le Lanthanum oxide e iai fo'i ana fa'aoga taua i vaega e pei o mea e teu ai le haitorosene ma sela suau'u. Mo se fa'ata'ita'iga, e mafai ona fa'aogaina le lanthanum-nickel alloys mo le teuina o le haitorosene.
