thorium(IV) oxide (Thorium Dioxide) (ThO2) pauka Purity Min.99%
Thorium Dioxide (ThO2), kapaiathorium(IV) oxide, he kumu Thorium hiki ole ke hooheheeia. He paʻa crystalline a keʻokeʻo pinepine a melemele paha. ʻIke ʻia hoʻi ʻo thoria, hana nui ʻia ma ke ʻano he huahana o ka lanthanide a me ka hana uranium. ʻO Thorianite ka inoa o ke ʻano mineralogical o thorium dioxide. Nui ka waiwai o Thorium i ke aniani a me ka hana keramika ma ke ʻano he puaʻa melemele ʻulaʻula ma muli o kona hoʻomanaʻo maikaʻi loa. ʻAʻole hiki ke hoʻokuʻi ʻia nā hui oxide i ka uila.
