Korundum Chrome (sidoo kale loo yaqaan corundum pink) waxaa lagu sameeyaa falcelin kiimikaad ee aluminium-chrome-cagaaran iyo warshado heerkul sare ah oo ka sarreeya 2000 darajo.Qadar gaar ah oo chromium oxide ah ayaa lagu daraa inta lagu jiro habka dhalaalidda, taas oo ah guduud khafiif ah ama ubax.
Chromium corundum wuxuu ku fiican yahay waxqabadka dhamaystiran oo ay ku jiraan qallafsanaanta sare, adkaanta sare, daahirsanaanta sare, is-afaynta aad u fiican, awoodda wax lagu shiido, jiilka kulaylka hooseeya, waxtarka sare, caabbinta aashitada iyo alkali, caabbinta heerkulka sare, iyo xasilloonida kulaylka wanaagsan.
Ku darida curiyaha kiimikaad ee Cr ee chrome corundum waxay wanaajisaa adkaanta qalabkeeda xadhkaha.Waxay la mid tahay corundum cad ee adayga laakiin ka sarreeya adayga.Aaladaha abrasive ee ka samaysan corundum chrome waxay leeyihiin adkeysi wanaagsan iyo dhammayn sare.Waxaa si weyn loo isticmaalaa in abrading, shiidi, polishing, si sax ah cammuudda tuuraya, alaabta lagu buufiyo, qaade kiimikaad, ceramics gaar ah iyo wixii la mid ah.Goobaha lagu dabaqi karo waxaa ka mid ah: qalabka cabbiraadda, dunta mashiinada, qaybaha qalabka, shiididda saxda ah ee wax soo saarka dunta iyo qaabka.
Korundum-ka chrome-ka waxa uu leeyahay viscosity sare iyo meel-marin wanaagsan taas oo ay ugu wacan tahay qaybta galaaska ka kooban chromium oxide, taas oo inta badan ka hortagi karta nabaad-guurka iyo dhexgalka dhalaalidda.Waxa kale oo si weyn loogu isticmaalaa goobaha heerkulka sare leh ee leh jawi adag, oo ay ku jiraan foornooyinka birta ah ee aan birta ahayn, foornooyinka dhalaalinta dhalada ah, kaarboonka madow ee kaarboon, gubi qashinka iyo kabka dib u celinta.
