Brick alumina dị elu bụ ụdị refractory, ihe bụ isi ya bụ Al2O3. Ọ bụrụ na ọdịnaya Al2O3 dị elu karịa 90%, a na-akpọ ya brik corundum. N'ihi akụrụngwa dị iche iche, ụkpụrụ nke mba dị iche iche anaghị agbanwe agbanwe. Dịka ọmụmaatụ, na mba Europe, njedebe dị ala nke ọdịnaya Al2O3 maka nnukwu alumina refractories bụ 42%. Na China, a na-ekewa ọdịnaya Al2O3 na brik alumina dị elu na ọkwa atọ: ọkwa I - Al2O3 ọdịnaya> 75%; ọkwa II - Al2O3 ọdịnaya bụ 60-75%; ọkwa III - Ọdịnaya Al2O3 bụ 48-60%.
Atụmatụ:
1. High refractoriness
2.High okpomọkụ ike
3.High thermal kwụsie ike
4. Neutral refractory
5.Good iguzogide acid na isi slag corrosion
6.High refractoriness n'okpuru ibu
7.High okpomọkụ creep resistance
8.Low pụtara porosity
