Ubukorikori bw'ibyuma ni ubutare bwometseho icyuma, butuma bihuza neza n'ibice by'ibyuma. Ubu buryo busanzwe bukubiyemo gushyira icyuma hejuru yubutaka, hanyuma hagakurikiraho ubushyuhe bwo hejuru kugirango uhuze ceramic nicyuma. Ibikoresho bisanzwe byifashishwa birimo molybdenum-manganese na nikel. Bitewe nubukorikori bwiza cyane, ubushyuhe bwo hejuru, hamwe no kurwanya ruswa, ububumbyi bwumuringa bukoreshwa cyane mubikoresho bya elegitoroniki n’inganda z’amashanyarazi, cyane cyane mu bikoresho bya elegitoroniki, icyuma cya elegitoroniki, sensor, na capacator.

Ububiko bwumuringa bukoreshwa cyane mubisabwa bisaba ubushyuhe bwo hejuru, imbaraga za mashini, hamwe n amashanyarazi meza. Kurugero, zikoreshwa mugupakira ibikoresho bya elegitoroniki ya vacuum, insimburangingo yibikoresho bya semiconductor power, ibyuma bishyushya ibikoresho bya laser, hamwe nuburaro bwibikoresho byitumanaho byihuta. Gufunga no guhuza ibyuma byabugenewe byerekana neza ibyo bikoresho mubidukikije bikabije.
