Ny maha samy hafa ny magnesia alumina biriky sy biriky alumina avo

1. Refractoriness: Ny refractoriness ny magnesia-aluminium biriky dia ambony kely noho ny avo-alumina biriky. Ny biriky refractory ny magnesia-aluminium biriky dia matetika ambony noho ny 2000 ℃, raha avo-alumina biriky amin’ny ankapobeny mahatratra 1750 ~ 1790 ℃.

2. Magnesia alumina biriky dia alkaline refractory fitaovana, izay afaka mahomby manohitra ny erosion ny alkaline slag, raha avo alumina biriky dia tsy miandany refractory fitaovana amin’ny tsara alkali fanoherana sy asidra fanoherana.
