thorium (IV) oxide (Thorium Dioxide) (ThO2) hmoov Purity Min.99%
Thorium Dioxide (ThO2), kuj hu uathorium (IV) oxide, yog ib qho khoom siv Thorium uas tsis yaj tau zoo thiab ruaj khov heev. Nws yog ib qho khoom siv crystalline thiab feem ntau yog dawb lossis daj. Kuj tseem hu ua thoria, nws feem ntau yog tsim los ntawm kev tsim lanthanide thiab uranium. Thorianite yog lub npe ntawm daim ntawv mineralogical ntawm thorium dioxide. Thorium muaj nqis heev hauv kev tsim iav thiab ceramic ua cov xim daj ci vim nws qhov kev cuam tshuam zoo tshaj plaws. High Purity (99.999%) Thorium Oxide (ThO2) Hmoov ntawm 560 nm. Cov tshuaj oxide tsis ua rau hluav taws xob.
