Chrome corundum (fa'aigoaina fo'i o le korundum piniki) e faia e ala i fa'ama'i vaila'au o metallurgical chrome-lanumeamata ma alumina alamanuia i le maualuga o le vevela i luga ole 2000 tikeri.O se aofaiga o le chromium oxide e faʻaopoopoina i le taimi o le faʻafefeteina, o le lanu viole poʻo le rosa.
Chromium corundum e sili atu i le faʻatinoga atoatoa e aofia ai le maualuga o le maʻaʻa, maualuga le malosi, maualuga le mama, sili ona lelei le faʻamaʻaina o le tagata lava ia, malosi malosi e olo ai, faʻatupuina le vevela, maualuga le malosi, acid and alkali resistance, maualuga le vevela o le vevela, ma le mautu lelei o le vevela.
O le fa'aopoopoina o le elemene vaila'au Cr i le chrome corundum e fa'aleleia atili ai le malosi o ana mea faigaluega fa'amalosi.E tali tutusa ma le pa'epa'e korundum i le ma'a'a ae maualuga i le ma'a'a.O meafaigaluega abrasive e faia i le chrome corundum e lelei le tumau ma maualuga maualuga.E faʻaaogaina lautele i le abrading, oloina, faʻalelei, saʻo le lafoina o le oneone, mea faʻapipiʻi, vailaʻau faʻamaʻi kemisi, ceramics faʻapitoa ma isi.Fa'atatauga fanua e aofia ai: fuaina meafaigaluega, masini meafaigaluega spindles, vaega meafaigaluega, olo sa'o i filo gaosiga ma faʻataʻitaʻiga.
O le chrome corundum e maualuga le viscosity ma le faʻaogaina lelei ona o le chromium oxide-o loʻo i ai le tioata, lea e mafai ona puipuia tele ai le tafia ma le ulu o le paʻu uʻamea.E faʻaaogaina lautele foi i fanua vevela maualuga ma siosiomaga faigata, e aofia ai ogaumu metallurgy e le ferrous, ogaumu liusuavai tioata, reactors uliuli carbon, incinerators lapisi ma refractory castables.
