Kodi Thorium Dioxide (ThO2) amagwiritsidwa ntchito chiyani?
Thorium dioxide (thoria) yakhala ikugwiritsidwa ntchito muzitsulo zotentha kwambiri, zovala za gasi, mafuta a nyukiliya, kupopera moto, crucibles, magalasi owoneka bwino osagwiritsa ntchito silicia, catalysis, filaments mu nyali za incandescent, cathodes mu machubu a electron ndi arc-melting electrodes.Mafuta a nyukiliyaThorium dioxide (thoria) itha kugwiritsidwa ntchito mu zida za nyukiliya ngati ma pellets a ceramic, omwe amakhala mu ndodo zamafuta a nyukiliya zovekedwa ndi aloyi a zirconium. Thorium si fissile (koma ndi "chonde", kuswana fissile uranium-233 pansi pa bombardment nyutroni);AloyiThorium dioxide imagwiritsidwa ntchito ngati chokhazikika mu ma elekitirodi a tungsten mu TIG welding, machubu a elekitironi, ndi injini zama turbine za ndege.CatalysisThorium dioxide ilibe phindu lililonse ngati chothandizira malonda, koma ntchito zoterezi zafufuzidwa bwino. Ndiwothandizira pakupanga mphete yayikulu ya Ruzicka.Ma radiocontrast agentsThorium dioxide inali chinthu chachikulu mu Thorotrast, chomwe chimadziwika kuti radiocontrast chomwe chimagwiritsidwa ntchito popanga cerebral angiography, komabe, chimayambitsa khansa yachilendo (hepatic angiosarcoma) zaka zambiri pambuyo pa kuwongolera.Kupanga magalasiMukawonjezeredwa ku galasi, thorium dioxide imathandiza kuonjezera chiwerengero chake cha refractive ndi kuchepetsa kubalalitsidwa. Magalasi oterowo amapeza ntchito m'magalasi apamwamba kwambiri amakamera ndi zida zasayansi.
