Babban tubali na alumina wani nau'i ne na refractory, babban bangaren wanda shine Al2O3. Idan abun ciki na Al2O3 ya fi 90% girma, ana kiran shi tubalin corundum. Saboda albarkatu daban-daban, ma'auni na ƙasashe daban-daban ba su da daidaituwa gaba ɗaya. Alal misali, a cikin ƙasashen Turai, ƙananan iyaka na abun ciki na Al2O3 don manyan alumina refractories shine 42%. A kasar Sin, abun ciki na Al2O3 a cikin bulo mai tsayi na alumina gabaɗaya ya kasu kashi uku: Matsayi na I - abun ciki na Al2O3> 75%; aji II - Al2O3 abun ciki shine 60-75%; aji III - Al2O3 abun ciki shine 48-60%.
Siffofin:
1. High refractoriness
2.High zafin jiki ƙarfi
3.High thermal kwanciyar hankali
4.Neutral refractory
5.Good juriya ga acid da asali slag lalata
6.High refractoriness karkashin kaya
7.High zazzabi juriya creep
8.Low bayyananne porosity
