thorium(IV) oxide (Thorium Dioxide) (ThO2) pauta Mama Min.99%

Fa'amatalaga Puupuu:

Torium Dioxide (ThO2), ua ta'ua foithorium(IV) oxide, o se puna Thorium e matua le mafai ona fa'afefeteina. O se tioata tioata ma e masani ona paʻepaʻe pe samasama i le lanu. E taʻua foi o le thoria, e gaosia tele o se mea e maua mai i le gaosiga o le lanthanide ma le uranium. Torianite o le igoa ole mineralogical form of thorium dioxide. O le Thorium e maualuga lona taua i le gaosiga o tioata ma sima e pei o se lanu samasama susulu ona o lona faʻataʻitaʻiga sili ona lelei. O fa'aputuga o le oxide e le fa'aoso i le eletise.

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 le silisia, catalysis, filaments i moli moli, cathodes i paipa eletise ma eletise eletise.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 la'au faaniukilia o lo'o fa'aofuina i zirconium alloys. O le Thorium e le o se mea faʻapitoa (ae e "tamaʻi", faʻatupuina le 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 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 o 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.
