Utoto wa iron oxide ndi mtundu wa utoto womwe umatha 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, kutengera iron oxides. Pakati pawo, iron oxide wofiira ndiye utoto waukulu (womwe umakhala pafupifupi 50% ya utoto wa iron oxide), ndipo mica iron oxide yomwe imagwiritsidwa ntchito ngati utoto wotsutsana ndi dzimbiri ndi magnetic iron oxide yomwe imagwiritsidwa 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 dioxide komanso utoto waukulu kwambiri wa inorganic. Zoposa 70% za utoto wonse wa iron oxide womwe umadyedwa umakonzedwa ndi njira zopangira mankhwala, zomwe zimadziwika kuti synthetic iron oxide. Synthetic iron oxide imagwiritsidwa ntchito kwambiri muzomanga, zokutira, mapulasitiki, zamagetsi, fodya, mankhwala, rabara, zoumba, inki yosindikizira, zinthu zamaginito, kupanga mapepala ndi minda ina chifukwa cha kuyera kwake kwakukulu kopanga, kukula kwa tinthu tofanana, chromatography yayikulu, mitundu ingapo, mtengo wotsika, wopanda poizoni, utoto wabwino kwambiri komanso mawonekedwe ogwiritsira ntchito, komanso mphamvu zoyamwa za ultraviolet. Utoto wa iron oxide umagwiritsidwa ntchito kwambiri mu zophimba, utoto, ndi inki chifukwa cha kusawononga, kusatulutsa magazi, mtengo wotsika, komanso kuthekera kopanga mitundu yosiyanasiyana. Zophimba zimapangidwa ndi zinthu zopangira filimu, utoto, zodzaza, zosungunulira, ndi zowonjezera. Zapangidwa kuchokera ku zophimba zochokera ku mafuta mpaka zophimba zopangidwa ndi resin, ndipo zophimba zosiyanasiyana sizingathe kuchita popanda kugwiritsa ntchito utoto, makamaka utoto wa iron oxide, womwe wakhala mtundu wofunikira kwambiri wa utoto mumakampani ophimba.

Mitundu ya utoto wa iron oxide yomwe imagwiritsidwa ntchito popanga utoto ndi monga chikasu chachitsulo, chofiira chachitsulo, bulauni chachitsulo, chakuda chachitsulo, mica chitsulo oxide, chobiriwira chachitsulo chowonekera, chofiira chachitsulo chowonekera, ndi zinthu zowala, zomwe chikasu chofiira chachitsulo ndicho chofunikira kwambiri pamitundu yambiri komanso yosiyanasiyana.

Chitsulo chofiira chachitsulo chili ndi mphamvu yabwino kwambiri yolimbana ndi kutentha, sichisintha mtundu pa 500 ℃, ndipo sichisintha kapangidwe ka mankhwala ake pa 1200 ℃, zomwe zimapangitsa kuti chikhale chokhazikika kwambiri. Chimatha kuyamwa kuwala kwa ultraviolet mu dzuwa, kotero chimakhala ndi mphamvu yoteteza pa utoto. Sichimasungunuka ndi asidi, alkalis, madzi, ndi zosungunulira, zomwe zimapangitsa kuti chikhale cholimba komanso cholimba.
