Iron okusayidi ndi ambiri ntchito inorganic pawiri ndi zotsatirazi katundu ndi katundu: Thupi katundu: Iron okusayidi nthawi zambiri mu mawonekedwe olimba ndipo amabwera mu mitundu yosiyanasiyana, monga wofiira (Fe2O3), wachikasu (α-Fe2O3), wakuda (Fe3O4), ndi zofiirira (FeO). Amakhala ndi mawonekedwe osiyanasiyana a kristalo ndi magawo a lattice. Magnetism: Fe3O4 (maginito chitsulo ore) mu chitsulo okusayidi amaonetsa maginito zoonekeratu ndipo ali ndi reversible mkulu-kutentha maginito kusintha mawonekedwe. Izi zimapangitsa kuti azigwiritsidwa ntchito kwambiri m'magawo monga maginito ndi maginito kujambula media. Chemical properties: Iron oxide ndi chinthu chosasungunuka m'madzi chokhala ndi kukhazikika kwamankhwala. Imalimbana kwambiri ndi ma acid ndi alkalis. Kukhazikika kwamtundu: Iron oxides m'mitundu yosiyanasiyana nthawi zambiri imakhala ndi kukhazikika kwamtundu, zomwe zimapangitsa kuti azigwiritsidwa ntchito kwambiri popanga utoto, utoto ndi utoto. Optical properties: Iron oxide imatha kuyamwa ndi kuwonetsa kuwala mu bandi yowoneka bwino, yomwe imapangitsa kuti igwiritsidwe ntchito popanga zinthu zowoneka bwino, inki ndi zopangira. Kukhazikika kwamafuta: Iron oxide imakhala ndi kukhazikika kwamafuta ambiri ndipo imatha kusunga kukhazikika kwa zinthu zake zakuthupi ndi zamankhwala m'malo otentha kwambiri. Zonsezi, okusayidi yachitsulo imakhala ndi zinthu zosiyanasiyana zomwe zimapangitsa kuti azigwiritsidwa ntchito kwambiri m'madera ambiri, monga sayansi yakuthupi, kukonzekera mankhwala, kuteteza chilengedwe, ndi zina zotero.
