Kodi Thorium Dioxide (ThO2) imagwiritsidwa ntchito pa chiyani?
Thorium dioxide (thoria) yagwiritsidwa ntchito mu zoumba zotentha kwambiri, mantle a gasi, mafuta a nyukiliya, kupopera malawi, zophikira, magalasi osakhala a silicia, catalysis, filaments mu nyali za incandescent, ma cathodes m'machubu a ma electron ndi ma electrodes osungunuka a arc.Mafuta a nyukiliyaThorium dioxide (thoria) ingagwiritsidwe ntchito mu ma reactor a nyukiliya ngati ma pellets amafuta a ceramic, omwe nthawi zambiri amakhala mu ndodo zamafuta a nyukiliya zokhala ndi zirconium alloys. Thorium si fissile (koma ndi "yobiriwira", yomwe imabala fissile uranium-233 pansi pa bombardment ya neutron);Ma aloyiThorium dioxide imagwiritsidwa ntchito ngati chokhazikika mu ma electrode a tungsten mu TIG welding, ma electron tubes, ndi injini za gasi za ndege.KukonzaThorium dioxide ilibe phindu lililonse ngati chothandizira malonda, koma ntchito zotere zafufuzidwa bwino. Ndi chothandizira mu kapangidwe ka mphete yayikulu ya Ruzicka.Zothandizira za RadiocontrastThorium dioxide inali chinthu chachikulu chomwe chimagwiritsidwa ntchito mu Thorotrast, chomwe kale chinali chofala kwambiri pochiza matenda a ubongo, komabe, chimayambitsa khansa yosowa kwambiri (hepatic angiosarcoma) patatha zaka zambiri kuchokera pamene chinaperekedwa.Kupanga magalasiAkawonjezeredwa ku galasi, thorium dioxide imathandiza kuonjezera refractive index yake ndikuchepetsa kufalikira. Galasi lotere limagwiritsidwa ntchito m'magalasi apamwamba kwambiri a makamera ndi zida zasayansi.
