Fa'amatalaga: O le Tungsten lanumoana e tele lava ina fefiloi; Afifiina: I totonu o talipalau u'amea ma taga palasitika fa'alua i totonu e 200kgs le mamafa i le talipalau ta'itasi.
O le a le mea e faʻaaogaina ai le Tungsten Trioxide?
Tungsten Trioxide (WO₃)o se u'amea 'okesaite' e tele ona fa'aoga ma e maualuga lona fa'atinoga e iai ona uiga fa'akemikolo, va'ai, ma eletise tulaga ese. E avea o se mea taua e amata ai ma se fa'aputuga aoga i le tele o fa'aoga fa'atekonolosi masani ma fa'aonaponei.
O la matou Tungsten Trioxide mama maualuga ua mamanuina mo le tulaga silisili i vaega nei:
1. Mea Muamua Fa'apisinisi
O le Tungsten Trioxide o le mea autū lea mo le tele o oloa e fa'avae i le tungsten.
* Tungsten U'amea ma le Tungsten Carbide: Fa'aitiitia e gaosia ai le pauta u'amea tungsten, lea e fa'aaogaina e gaosia ai u'amea fa'amamago, meafaigaluega tungsten carbide, ma vaega e maualuga le mafiafia.
* Tungstate Compounds: Fa'aputuina i ni tungstates eseese (e pei o le calcium tungstate, sodium tungstate), e taua tele i le tele o fa'aoga i lalo ifo.
2. Lanu ma Mea Fa'a'aoga e Fa'aaoga
I le fa'aaogaina o lona lanu samasama malosi, o le WO₃ o se pigment inorganic taua.
* Omea ma Vali: E tu'uina atu ai se lanu samasama mautu, umi, ma susulu i vali vali, omea ma vali tau alamanuia. E taua tele ona o lona tumau i le vevela ma le tete'e atu i vaila'au.
3. Meafaitino Fa'aonaponei ma Tekonolosi Fa'aonaponei
O meatotino aoga o le WO₃ ua avea ai ma mea autu i faʻafouga faʻatekonolosi faʻaonaponei.
* Fa'amalama Atamai ma Masini Electrochromic: I le tulaga o ni ata manifinifi, e mafai e le Tungsten Trioxide ona suia lona lanu ma le manino pe a fa'aogaina se voltage eletise la'ititi. O lenei aafiaga electrochromic e fa'aaogaina i "fa'amalama atamai" e sefe ai le malosi mo fale ma ta'avale, fa'apea fo'i ma fa'aaliga ma fa'ata va'ai i tua.
* Sensors Kasa: E suia lona fa'avevela eletise pe a iai ni kasa fa'apitoa (e pei o le nitrogen oxides, ozone), ma avea ai ma mea sili ona lelei ma maaleale tele mo sensors kasa malo e fa'aaogaina i le mata'ituina o le siosiomaga, saogalemu fa'apisinisi, ma faiga e pulea ai le kasa o ta'avale.
* Photocatalysis & Malosiaga o le La: O le Tungsten Trioxide o se semiconductor photocatalyst lauiloa. E mitiia se vaega tele o le fusi o le la (e aofia ai le malamalama lanumoana) ma e mafai ona faʻaaogaina mo faʻaoga e pei o le faʻamamaina o le ea/vai (faʻaleagaina o mea leaga faʻalenatura) ma le atinaʻeina o sela photoelectrochemical mo le vaeluaina o le vai mai le la.
4. Fa'aoga Fa'apitoa ma Fa'avae
* Mea e Tete'e atu ai i le Mu: O mea tungstate e maua mai i le WO₃ e fa'aaogaina e fa'aalia ai uiga e tete'e atu ai i le afi i ie, laupapa, ma isi meafaitino.
* X-Ray Scintillators: O le Calcium tungstate (CaWO₄), e gaosia mai le WO₃, o se phosphor masani e faʻaaogaina i pupuni faʻamalosia o le X-ray ma masini e iloa ai le ave o le la, e liua ai le malosiaga o le X-ray i le malamalama vaaia.

Fa'amanuiaga Autū o La Matou Tungsten Trioxide:
* Mama Maualuga: Mautinoa le fa'atinoga faifai pea ma le tulaga lelei sili atu i le fa'agasologa ma fa'aoga i lalo.
* Feavea'i: E galue o se mea fa'avae autu mo vaila'au fa'akemikolo ma se mea aoga taua tele.
* Faiga Fa'apitoa: E maua i vasega eseese, e aofia ai pauta nano-structured ma precursors manifinifi-film e fa'afetaui ai mana'oga fa'apitoa o R&D ma alamanuia.
Teena o Fa'amatalaga: O fa'amatalaga o lo'o tu'uina atu iinei e mo na'o fa'amatalaga fa'amatala. O le tiutetauave lea a le tagata fa'aoga e fuafua ai le talafeagai o lenei oloa mo lana fa'aoga fa'apitoa.
