Ihe dị iche n’etiti brik alumina magnesia na brik alumina dị elu

1. Refractoriness: Ntugharị nke brik magnesia-aluminom dị ntakịrị karịa nke brik alumina dị elu. The refractory brik nke magnesia-aluminom brik na-emekarị elu karịa 2000 ℃, mgbe elu-alumina brik n’ozuzu iru 1750 ~ 1790 ℃.

2. Magnesia alumina brik bụ alkaline refractory ihe, nke nwere ike n’ụzọ dị irè na-eguzogide ozize nke alkaline slag, mgbe elu alumina brik na-anọpụ iche refractory ihe na magburu onwe alkali iguzogide na acid iguzogide.
