O le ā le mea e fa'aaogā i ai le Thorium Dioxide (ThO2)?
O le Thorium dioxide (thoria) ua fa'aaogaina i keramika vevela maualuga, kesi, penisini fa'aniukilia, fa'asusuina o le afi, ipu fa'asusu, tioata opitika e le o silicia, fa'aoso, filaments i lamepa incandescent, cathodes i paipa eletise ma electrodes e fa'amaluluina ai le arc.Suau'u fa'aniukiliaE mafai ona fa'aaogaina le Thorium dioxide (thoria) i totonu o reactors fa'aniukilia e pei o ni pellets seramika mo suau'u, e masani ona i totonu o ni'o suau'u fa'aniukilia ua ufiufi i ni zirconium alloys. E le o se fissile le Thorium (ae e "fanafanau", e fa'atupuina ai le fissile uranium-233 i lalo o le neutron bomb);AlloysE fa'aaogaina le Thorium dioxide o se mea e fa'amautu ai le tungsten electrodes i le TIG welding, electron tubes, ma afi turbine kesi a va'alele.Fa'aolaolaE toetoe lava a leai se aogā o le Thorium dioxide e fai ma mea fa'atupu fa'apisinisi, ae o ia fa'aoga ua mae'a su'esu'eina lelei. O se mea fa'atupu fa'alavelave i le fa'aputuga o mama tetele o Ruzicka.O sui e fa'aalia ai le eseesega o le leitioO le Thorium dioxide o le elemene autū lea i le Thorotrast, o se vailaʻau faʻaalia i luga o le radiocontrast sa masani ona faʻaaogaina mo le angiography o le faiʻai, peitaʻi, e mafua ai se ituaiga kanesa e seasea tupu (hepatic angiosarcoma) i le tele o tausaga talu ona faʻaaogaina.Gaosiga tioataA fa'aopoopo i le tioata, e fesoasoani le thorium dioxide e fa'ateleina lona refractive index ma fa'aitiitia ai le dispersion. O ia tioata e fa'aaogaina i tioata maualuga lelei mo meapueata ma meafaigaluega fa'asaienisi.
