shown in Figs. 11 and 12. The thermal conductivity was decreased with porosity increases from 0.5 to 0.4 W/m K for bauxite additions and to 0.36 W/m K for metakaolin addi-tions. The effect of porosity is important; when the thermal conductivity of the air is negligible compared to the solid dramatically reduce thermal conductivity.

Oct 15, 2018· Addition of zircon or fused zirconia-mullite (aggregate or powder) resulted in the decrease of thermal conductivity as compared to bauxite-SiC refractories. The presence of zircon is not able to decompose at 1500 °C, leading to the weak chemical bond and inferior mechanical properties.
