Chrome corundum (izwi kandi nka pink corundum) ikorwa nubushakashatsi bwa chimique metallurgical chrome-icyatsi n’inganda alumina ku bushyuhe buri hejuru ya dogere 2000.Umubare munini wa chromium oxyde wongeyeho mugihe cyo gushonga, ni ibara ryijimye cyangwa roza.
Chromium corundum irusha abandi gukora neza harimo ubukana bwinshi, ubukana bwinshi, isuku nyinshi, ubwiza bwo kwikarishye, ubushobozi bwo gusya cyane, kubyara ubushyuhe buke, gukora neza, aside na alkali, kurwanya ubushyuhe bwinshi, hamwe nubushyuhe bwiza bwumuriro.
Kwiyongera kwimiti ya Cr muri chrome corundum itezimbere ubukana bwibikoresho byayo.Irasa na corundum yera mubukomere ariko hejuru mubukomere.Ibikoresho byo gukuramo bikozwe muri chrome corundum bifite igihe kirekire kandi birangiye.Ikoreshwa cyane mugukuraho, gusya, gusya, guterera neza umucanga, ibikoresho byo gutera, gutwara imiti ya catalizike, ububumbyi bwihariye nibindi.Imirima ikoreshwa irimo: ibikoresho byo gupima, ibikoresho bya mashini izunguruka, ibice byibikoresho, gusya neza mubikorwa byakozwe hamwe na moderi.
Chrome corundum ifite ubukonje bwinshi kandi bworoshye neza bitewe na chromium oxyde irimo ibirahuri, bishobora gukumira ahanini isuri no kwinjira mumashanyarazi.Irakoreshwa kandi cyane mumirima yubushyuhe bwo hejuru hamwe nibidukikije bikaze, harimo itanura rya metallurgie idafite ferrous, itanura ryo gushonga ibirahure, reaction yumukara wa karubone, gutwika imyanda hamwe n’ibikoresho byangiza.
