Utoto wa iron oxide ndi mtundu wa utoto wokhala ndi kufalikira bwino, kukana kuwala bwino komanso kukana nyengo. Utoto wa iron oxide makamaka umatanthauza mitundu inayi ya utoto, womwe ndi iron oxide wofiira, iron wachikasu, iron wakuda ndi iron brown, ndipo iron oxide oxide ndiye chinthu chofunikira. Pakati pawo, iron oxide wofiira ndiye mtundu waukulu (womwe umapanga pafupifupi 50% ya utoto wa iron oxide). Iron oxide woyipa womwe umagwiritsidwa ntchito ngati utoto wotsutsana ndi dzimbiri ndi magnetic iron oxide womwe umagwiritsidwa ntchito ngati zida zojambulira maginito nawonso ali m'gulu la utoto wa iron oxide. Iron oxide ndi utoto wachiwiri waukulu kwambiri wa inorganic pambuyo pa titanium white, komanso utoto waukulu kwambiri wa inorganic. Pa mitundu yonse ya iron oxide yomwe imagwiritsidwa ntchito, yoposa 70% imakonzedwa ndi mankhwala, omwe amatchedwa synthetic iron oxide. Synthetic iron oxide imagwiritsidwa ntchito kwambiri muzomanga, zokutira, mapulasitiki, zamagetsi, fodya, mankhwala, rabara, zoumba, inki, zida zamaginito, kupanga mapepala ndi zina chifukwa cha kuyera kwake kwakukulu, kukula kwa tinthu tofanana, mtundu wosiyanasiyana, mtengo wotsika, wopanda poizoni, utoto wabwino kwambiri komanso magwiridwe antchito, komanso magwiridwe antchito a ultraviolet.

Khalidwe 1. Kufalikira kwabwino
2. Kukana kuwala ndi nyengo bwino kwambiri
3. Kukana asidi
4. Kukana madzi
5. Kukana zosungunulira
6. Kukana mankhwala ena
7. Kukana kwa alkali
8. Kuchuluka kwa utoto wabwino, palibe kutuluka kwa utoto ndi kusamuka
