Thorium Dioxide (ThO2) siv rau dab tsi?
Thorium dioxide (thoria) tau siv rau hauv high-temperature ceramics, gas mantles, nuclear fuel, nplaim spraying, crucibles, non-silicia optical glass, catalysis, filaments in candescent lamps, cathodes in electron tubes and arc-melting electrodes.Nuclear fuelsThorium dioxide (thoria) tuaj yeem siv rau hauv cov tshuab hluav taws xob nuclear ua cov roj ntsha ceramic, feem ntau muaj nyob rau hauv cov roj hluav taws xob nuclear clad nrog zirconium alloys.Thorium tsis fissile (tab sis yog "fertile", yug me nyuam fissile uranium-233 nyob rau hauv neutron bombardment);Cov hlau nplaumThorium dioxide yog siv los ua tus stabilizer hauv tungsten electrodes hauv TIG vuam, electron tubes, thiab aircraft gas turbine engines.CatalysisThorium dioxide yuav luag tsis muaj nqi raws li kev lag luam catalyst, tab sis cov ntawv thov no tau raug tshawb xyuas zoo.Nws yog ib qho catalyst hauv Ruzicka loj nplhaib synthesis.Radiocontrast agentsThorium dioxide yog cov khoom tseem ceeb hauv Thorotrast, ib tus neeg siv xov tooj cua ib zaug siv rau cerebral angiography, txawm li cas los xij, nws ua rau tsis tshua muaj mob qog noj ntshav (hepatic angiosarcoma) ntau xyoo tom qab kev tswj hwm.Kev tsim iavThaum ntxiv rau iav, thorium dioxide pab ua kom nws cov refractive index thiab txo dispersion.Cov iav zoo li no pom daim ntawv thov hauv cov lo ntsiab muag zoo rau cov koob yees duab thiab cov cuab yeej tshawb fawb.
