Faʻaaogaina o le Cerium Oxide
O le Cerium Oxide, e taʻua foi o Ceria, e faʻaaogaina lautele i tioata, keramika ma gaosiga faʻamalosi. I le alamanuia tioata, ua manatu o le sili ona lelei tioata fa'alelei sui mo sa'o opitika fa'alelei. E fa'aaogaina fo'i e fa'aleaga tioata e ala i le fa'atumauina o le u'amea i lona tulaga u'amea. O le malosi o tioata Cerium-doped e poloka ai le malamalama ultra violet o loʻo faʻaaogaina i le gaosiga o tioata faʻafomaʻi ma faʻamalama vaalele. E fa'aoga fo'i e puipuia ai polymers mai le fa'apouliuligia i le susulu o le la ma taofia ai le fa'anenefu o tioata televise. E fa'aoga i vaega opitika e fa'aleleia ai le fa'atinoga. Ole mama maualuga Ceria e faʻaaogaina foi i phosphors ma dopant ile tioata.
O le cerium oxide, lea e taʻua foi o le ceria, o se tuufaatasiga e aofia ai elemene cerium ma le okesene ma le fua faʻamaʻi CeO2. E lanu samasama po'o le pa'epa'e pa'epa'e, e mautu i lalo o tulaga masani. O le Cerium oxide e iai le tele o faʻaoga, e aofia ai:
1. Catalyst: O le Cerium oxide o loʻo faʻaaogaina e fai ma faʻamalosi i le tele o faʻagasologa o pisinisi, e pei o le gaosiga o taavale afi mo faʻaliliuga faʻataʻitaʻi e faʻaitiitia ai faʻamalama ma mo le gaosiga o suauʻu gaosia.
2. Sui faʻamalo: O le Cerium oxide e faʻaaogaina e fai ma sui faʻamalo mo tioata ma isi mea. E aoga tele i le fa'amaluluina o luga o mea talatala ma aveese masiosi'ese.
3. Fuel additive: E mafai ona faʻaaogaina e fai ma faʻapipiʻi suauʻu e faʻaleleia ai le mama ma sili atu ona lelei le faʻafefe o le suauu.
4. Alamanuia tioata: O le Cerium oxide o loʻo faʻaaogaina i totonu o le fale tioata e gaosia ai tioata maualuga aua e mafai ona faʻateleina le faʻailoga faʻasolosolo ma faʻaleleia le tumau o le tioata.
5. gaosiga o le la: Cerium oxide o loʻo faʻaaogaina e fai ma mea faʻapipiʻi mo le gaosiga o sela sola. I le aotelega, o le cerium oxide e tele faʻaoga ma o se mea taua tele i pisinisi eseese ona o ona uiga tulaga ese.
6.used e pei o le tioata decolorizing sui ma le tioata polesi pauta. Faʻaaogaina foi e fai ma mea mata i le faia o le cerium uamea. Ole mama maualuga ole Cerium dioxide e taua tele ile fa'aogaina o mea e fa'afefeteina le eleele
