Thorium (IV) Oxide (Thorium Dioxide) (Tho2) Hmoov huv Min.99%
Thorium Dioxide (Tho2), tseem hu uathorium (iv) oxide, yog ib tug heev insoluble thermally ruaj khov thorium. Nws yog cov khoom siv khov kho thiab feem ntau dawb lossis daj hauv cov xim. Kuj tseem muaj lub npe hu ua Thoria, nws yog tsim tawm feem ntau yog cov khoom lag luam ntawm cov khoom lag luam ntawm caj pas thiab uranium ntau lawm. Thorianite yog lub npe ntawm cov pob zeb ntawm cov ntxhia dioxide. Thorium tau muaj txiaj ntsig heev hauv khob thiab tej hub thiab cov purity zoo Oxide cov tebchaw tsis ua haujlwm rau hluav taws xob.
