Chrome corundum (fa'aigoa o le piniki corundum) e faia i metallurgical grade chrome lanu meamata ma alamanuia alumina e pei o mea mata, ma chemically tali atu i se vevela maualuga i luga 2000 tikeri.E fa'aopoopoina le aofa'i o le chromium oxide i le taimi o le fa'afefeteina, o le lanu viole po'o le rosa.
O le faʻatinoga atoatoa o oloa chromium corundum o loʻo i ai uiga o le maualuga o le maaa, maualuga le malosi, maualuga le mama, sili ona lelei le faʻamalosiina o le tagata lava ia, malosi malosi e olo ai, faʻatupuina le vevela, maualuga le malosi, faʻamaʻi ma le alkali, maualuga le vevela, ma le mautu lelei.
I le chromium corundum, o le faʻaofiina o le elemene Cr e faʻaleleia ai le faigata o le abrasive.O le maaa e talitutusa ma le paʻepaʻe paʻepaʻe, ma o le malosi e maualuga atu nai lo le paʻepaʻe corundum.O mea faigaluega abrasive na gaosia e ia e lelei le tumau ma le mae'a maualuga.Fa'aaoga lautele i abrasives, olo, polesi mea, sa'o lafo oneone, spraying mea, vaila'au catalyst carriers, ceramics faapitoa, ma isi. O fanua talafeagai e aofia ai: sa'o olo o mea faigaluega fua, milo meafaigaluega masini, vaega meafaigaluega, threaded workpieces, ma faata'ita'i olo. .
O le chromium corundum e maualuga le viscosity ma le lelei o le tete'e atu ona o le chromium oxide-o lo'o i ai tioata vaega, lea e mafai ona puipuia tele le tafia ma le ulu o le slag liusuavai.E faʻaaogaina lautele foi i fanua vevela maualuga ma siosiomaga faigata, e aofia ai ogaumu metallurgy e le ferrous, ogaumu liusuavai tioata, carbon black reactors, lapisi incinerators, refractory castables ma isi vevela maualuga tetee ma puipuiga corrosion.
