O le a le mea e fa'aoga ai le Thorium Dioxide (ThO2)?
Thorium dioxide (thoria) ua faʻaaogaina i le vevela maualuga, ofu kesi, suauʻu faaniukilia, faʻafefe o le afi, faʻafefeteina, tioata mata e leai se silicia, catalysis, filaments i moli moli, cathodes i paipa eletise ma arc-melting electrodes.Suauu faaniukiliaO le Thorium dioxide (thoria) e mafai ona fa'aogaina i masini faaniukilia e pei o pellets suau'u sima, e masani lava ona i ai i totonu o u'amea faaniukilia o lo'o fa'aofuina i zirconium alloys.O le Thorium e le o se mea faʻapitoa (ae e "tamaoaiga", faʻatupuina fissile uranium-233 i lalo o le pomu neutron);AlloysThorium dioxide o loʻo faʻaaogaina e fai ma faʻamautu i tungsten electrodes i le TIG uelo, paipa eletise, ma afi afi afi vaalele.CatalysisO le Thorium dioxide e toetoe lava a leai se aoga e avea o se faʻasalalauga faʻapisinisi, ae o ia faʻaoga ua maeʻa suʻesuʻeina.O se faʻamalosi i le faʻaogaina o le mama tele a Ruzicka.Su'e fa'afeagai le leitioO le Thorium dioxide o le elemene autu lea i Thorotrast, o se mea e masani ona masani ai le radiocontrast agent na faʻaaogaina mo le cerebral angiography, peitaʻi, e mafua ai se ituaiga kanesa e seasea (hepatic angiosarcoma) i le tele o tausaga talu ona faʻaaogaina.Gaosi tioataPe a fa'aopoopo i le tioata, e fesoasoani le thorium dioxide e fa'ateleina lona fa'asinomaga fa'asolosolo ma fa'aitiitia le ta'ape.O ia tioata e maua le fa'aoga i tioata maualuga mo mea pu'eata ma mea fa'asaienisi.
