Ibara rya okiside y'icyuma ni ibintu bidafite umwimerere bikomoka kuri okiside y'icyuma, ari byo bintu bisanzwe by'ubutare byatunganyijwe kugira ngo bikore amabara atandukanye meza kandi arambye. Aya mabara akoreshwa cyane mu nganda zitandukanye bitewe n'imiterere yayo myiza y'amabara, kudahita bigaragara, kudahindagurika, no kwihanganira ikirere. Aza mu mabara menshi, harimo umutuku, umuhondo, umukara, n'umukara, kandi ashobora kubaho mu buryo busanzwe cyangwa gukorwa mu buryo bw'ubuhanga.

Mu nganda zikora amarangi n'amabara, ibara rya oxide y'icyuma rihabwa agaciro cyane kubera ubushobozi bwaryo bwo gutanga ibara rikomeye kandi rirambye ku buso bwo hanze no imbere. Rikoreshwa kandi muri pulasitiki no mu bicuruzwa bya kabutura kugira ngo ryongere ibara n'imbaraga, no mu kwisiga kugira ngo ritange amabara asa neza ku rufatiro, amaso, n'iminwa. Byongeye kandi, ibara rya oxide y'icyuma rikoreshwa mu bwubatsi mu gusiga irangi ibikoresho by'ubwubatsi nka sima, amatafari, n'amatafari, bikongera ubwiza bwabyo no kuramba.
