Alumina yumburawani nau'i ne na Al2O3 a matsayin babban albarkatun kasa, corundum (α-al2o3) a matsayin babban lokaci na crystalline na yumbu, a halin yanzu babban adadin kayan yumbu na oxide na duniya.Kuma sabodaalumina yumbukayan yumbu madaidaici ne mai jure lalacewa, ana amfani dashi ko'ina a kowane fanni na rayuwa.
Alumina yumburasuna da halaye masu zuwa:
1. Sanya juriya
Babban tsarkialumina ceramicssuna da juriya mai kyau sosai, wanda ya dace da sassan da aka yi amfani da su na dogon lokaci.
2, babu nakasu
Babban tsarkialumina ceramicskayan aiki ne masu kyau don daidaitattun sassa saboda suna da ƙarfin lanƙwasa ƙarfi da ƙarfin matsawa kuma ba su da sauƙin lalacewa.
