The thermal conductivity of three commercial‐quality alumina‐spinel castables containing 90–96 wt% A1 2 O 3 was measured in the range room temperature to 1000°C by a hot wire method. Experimental results indicate that the thermal conductivity increases with an increase in coarse aggregate content; higher corundum content and purer alumina aggregates are more important than coarse aggregate content for higher thermal conductivity of alumina‐spinel castables.
