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 ma 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 m'magawo monga zipangizo zomangira, zokutira, mapulasitiki, zamagetsi, fodya, mankhwala, rabara, zoumba, inki, zinthu zamaginito, kupanga mapepala, ndi zina zotero chifukwa cha kuyera kwake kwakukulu, kukula kwa tinthu tofanana, chromatography yayikulu, mitundu yosiyanasiyana, mtengo wotsika, katundu wopanda poizoni, utoto wabwino kwambiri komanso magwiridwe antchito, komanso magwiridwe antchito a UV.

Kugwiritsa ntchito utoto wa iron oxide popaka utoto zinthu za konkire kukuchulukirachulukira, ndipo kugwiritsa ntchito utoto wa iron oxide wofiira mu zinthu za konkire kuyenera kulabadira zizindikiro zotsatirazi. 1. Sankhani mtundu wabwino. Pali mitundu yambiri ya iron oxide wofiira, ndipo mitundu yake imayambira pa kuwala mpaka kuzama. Choyamba, sankhani mtundu womwe mukukhutira nawo. 2. Kuwonjezera utoto ku zinthu za konkire kungathandize kulimbitsa mphamvu ya konkire. Mukawonjezera kwambiri, zimakhudza kwambiri mphamvu ya konkire. Chifukwa chake mfundo ndi kuchepetsa kuchuluka kwa utoto womwe umawonjezeredwa momwe mungathere. Mphamvu ya utoto ya pigment ikachuluka, imachepa. Chifukwa chake kufunikira kwa utoto wa pigment kumakhala kwakukulu, kumakhala bwino. 3. Iron oxide wofiira imapangidwa ndi okosijeni wa mamba achitsulo mu acidic media. Ngati utoto wotsika kwambiri uli ndi acidity pang'ono, utoto wa acidic umakhudzana ndi simenti ya alkaline pamlingo winawake, kotero acidity ya iron oxide wofiira ikachepa, zimakhala bwino.

Fomula ya utoto wa iron oxide ndi chinthu chofunikira kwambiri pa zophimba zamakono ndi mafakitale a thermoplastic.

Chogulitsachi ndi choyenera kugwiritsa ntchito njira zachikhalidwe zosungunulira zinthu komanso zophimba zochokera m'madzi. Kuchepa kwa mafuta kumachitika kudzera mu njira yapadera yopukutira, yomwe imapanga kufalikira kwa tinthu tating'onoting'ono tating'onoting'ono komanso tinthu tating'onoting'ono tozungulira (polygonal). Kuchepa kwa mafuta ndi njira yofunika kwambiri popanga zophimba zolimba kwambiri komanso zopaka utoto zokhala ndi zinthu zolimba zambiri komanso inki za mankhwala osungunuka. Ndikofunikira kukhala ndi mchere wochepa kwambiri wosungunuka m'madzi, chifukwa utoto wa iron oxide umakhala wolimba kwambiri komanso umalimbana ndi nyengo.

Utoto wofiira wa iron oxide wosapangidwa umapangidwa ndi kutentha ndipo motero umayimira calcium oxide wofiira wa iron oxide womwe umasungunuka ndi kutentha.
Utoto uli ndi ubwino waukulu poyerekeza ndi zinthu zopangidwa mwachizolowezi.
