Abstract

Cordierite and corundum (α-Al2O3) are shown to be compatible phases below 1386±5° C. The reaction cordierite + corundum = mullite + spinel is reversible, but sluggish. Na2O and CaO (1.5 wt %) extend the stability of assemblages with mullite and spinel to slightly lower temperatures: 1364±5° C and 1380±8° C respectively, while 1.5 wt % iron oxide raises their stability temperature to 1397±8° C.
