Iipigment ze-iron oxide ziluhlobo olubalulekileyo lwe-inorganic colorants apho i-component esisiseko yi-iron oxides. Zibekwe njenge-inorganic pigments yesibini ngobukhulu emva kwe-titanium dioxide kunye ne-inorganic pigments eziphambili ezinemibala, zisetyenziswa kakhulu kwimveliso nakwimihla ngemihla.
Ngokwekhemikhali, ziquka ikakhulu iindidi ezine: i-iron oxide ebomvu, i-iron oxide emthubi, i-iron oxide emnyama, kunye ne-iron oxide brown. Phakathi kwazo, i-iron oxide ebomvu yeyona ixhaphakileyo, ibandakanya malunga ne-50% yee-iron oxide pigments iyonke. Ukongeza, i-micaceous iron oxide, esetyenziswa njenge-anti-rust pigment, kunye ne-magnetic iron oxide, kwizixhobo zokurekhoda ze-magnetic, nazo ziwela ngaphakathi kwee-iron oxide pigments. Iindidi ezahlukeneyo zee-iron oxide pigments zinika uluhlu olubanzi lwemibala ngenxa yeemeko ezahlukeneyo ze-oxidation yesinyithi. Umzekelo, i-iron oxide ebomvu, evela kwi-ferric oxide (Fe₂O₃), ibonakala ibomvu; i-iron oxide emthubi, evela kwi-ferric oxide emanzi (Fe₂O₃·H₂O), inombala otyheli; kwaye i-iron oxide emnyama, eyi-magnetite (Fe₃O₄), ibonisa imnyama.
Ngokuphathelele ukusebenza, ii-iron oxide pigments ziyamangalisa. Ukumelana kwazo ne-asidi kunye ne-alkali kugqwesileyo. Zizinzile kakhulu xa zithelekiswa nee-alkali ezahlukeneyo kunye nezinto zokwakha ezisetyenziswa rhoqo ezifana nesamente kunye ne-lime mortar, ngaphandle kokubangela umgubo wezinto zokwakha zesamente okanye ukuchaphazela amandla azo. Nangona kunjalo, ziyanyibilika kancinci kancinci kwi-asidi ezinamandla, ngakumbi xa kushushu kwaye kukho iimeko eziphezulu zoxinzelelo. Ngokuphathelele ukumelana nokukhanya kunye nobushushu, ii-iron oxide pigments eziqhelekileyo zizinzile ngaphakathi komgangatho othile wobushushu. Umzekelo, i-iron oxide etyheli ijika ibe bomvu - umbala xa idlula i-130°C, kwaye i-iron oxide red iyancipha ibe bomvu omnyama ngaphezulu kwe-300°C. Nangona kunjalo, amashishini amaninzi ngoku aphuhlise iimveliso ezisebenza kakuhle ezinokumelana namaqondo obushushu aphezulu. Ukumelana kwazo nemozulu kuyamangalisa, ngaphandle kwempembelelo ingako kwiimeko zemozulu ezifana nokubanda, ubushushu, ukoma, kunye nokufuma emoyeni, okwenza ukuba zibonakale kwiindawo zangaphandle. Ngaphezu koko, zizinzile kwiigesi ezingcolileyo, azinyibiliki emanzini, kwiioyile zeminerali, kwiioyile zemifuno, nakwii-organic solvents ezininzi, kwaye azibonisi ukungena.
