Korundum Chrome (sidoo kale loo yaqaan corundum pink) wuxuu ka samaysan yahay heerka birta ah ee chrome cagaaran iyo aluminium warshadeed sida alaab cayriin ah, oo kiimiko ahaan waxay uga falcelisaa heerkul sare 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.
Waxqabadka dhamaystiran ee alaabta chromium corundum waxay leedahay sifooyinka qallafsanaanta sare, adkaanta sare, daahirsanaanta sare, is-afaynta aad u fiican, awoodda wax lagu shiido, jiilka kulaylka hooseeya, waxtarka sare, caabbinta acid iyo alkali, caabbinta heerkulka sare, iyo xasilloonida kulaylka wanaagsan.
In chromium corundum, hordhaca ah curiyaha Cr hagaajinaysaa adkaanta xoqidda.Adayggu waxa uu la mid yahay kan korundum-ka cad, adayguna waxa uu ka sarreeyaa kan korundum cad.Aaladaha xoqan ee ay soo saartay waxay leeyihiin adkeysi wanaagsan iyo dhammayn heersare ah.Si ballaaran loo isticmaalo abrasives, shiidi, alaabta dhalaalaysa, ciid tuurista saxda ah, alaabta lagu buufiyo, sidayaal kiimikaad, dhoobada gaarka ah, iwm. Beeraha lagu dabaqi karo waxaa ka mid ah: shiida saxda ah ee qalabka wax lagu cabbiro, dunnida mishiinka qalabka, qaybaha qalabka, workpieces dunta, iyo model shiidi. .
Korondum-ka chromium waxa uu leeyahay viscosity sare iyo iska caabin wanaagsan oo ka bixitaan ah taas oo ay ugu wacan tahay qaybta galaaska ka kooban chromium oxide, taas oo inta badan ka hortagi karta nabaad-guurka iyo dhexgalka dhalada.Waxa kale oo si weyn loogu isticmaalaa beeraha heerkulka sare leh jawi adag, oo ay ku jiraan foornooyinka birta ah ee aan birta ahayn, foornooyinka dhalaalidda dhalada, kaarboonka madow ee kaarboonka, gubi qashinka qashinka, qalfoofka refractory iyo caabbinta heerkulka sare ee kale iyo ilaalinta daxalka.
