I-Chrome corundum (eyaziwa nangokuthi i-pink corundum) yenziwa ukusabela kwamakhemikhali kwe-metallurgical chrome-green kanye ne-alumina yezimboni ezingeni lokushisa eliphezulu elingaphezu kwama-degree angu-2000.Inani elithile le-chromium oxide liyengezwa phakathi nenqubo yokuncibilika, okunsomi ngokukhanyayo noma i-rose.
I-Chromium corundum ihamba phambili ekusebenzeni okuphelele okuhlanganisa ubulukhuni obuphezulu, ukuqina okuphezulu, ukuhlanzeka okuphezulu, ukuzilola okuhle kakhulu, ikhono eliqinile lokugaya, ukukhiqiza ukushisa okuphansi, ukusebenza kahle okuphezulu, ukumelana ne-asidi ne-alkali, ukumelana nezinga lokushisa eliphezulu, nokuzinza okuhle kokushisa.
Ukwengezwa kwento yamakhemikhali u-Cr ku-chrome corundum kuthuthukisa ukuqina kwamathuluzi ayo abrasive.Ifana ne-white corundum ngobulukhuni kodwa iphakeme ngokuqina.Amathuluzi abrasive enziwe nge-chrome corundum anokuqina okuhle nokuqeda okuphezulu.Isetshenziswa kabanzi ku-abrading, ukugaya, ukupholisha, ukuphonsa isihlabathi ngokunembile, izinto zokufafaza, umthwali we-catalyst wamakhemikhali, izitsha zobumba ezikhethekile nokunye.Izinkambu ezisebenzayo zifaka: amathuluzi okulinganisa, izinsimbi zokuphotha zethuluzi lomshini, izingxenye zamathuluzi, ukugaya okunembayo ekukhiqizweni okunentambo kanye nemodeli.
I-chrome corundum ine-viscosity ephezulu kanye nokungena kahle ngenxa yengxenye yengilazi equkethe i-chromium oxide, engavimbela kakhulu ukuguguleka nokungena kwe-slag encibilikisiwe.Ibuye isetshenziswe kabanzi ezindaweni zokushisa eziphakeme ezinemvelo enokhahlo, okuhlanganisa iziko le-metallurgy ezingezona ayoni, izindawo zokuncibilikisa ingilazi, ama-carbon black reactors, izishisi zikadoti kanye nezinto ezilahlwayo eziphikisayo.
