Abstract
The thermal effusivities of the AlO1.5R2OSiO(2 R=Li, Na)melts were measured by the frontheating frontdetection laser flash method. The thermal conductivities of the AlO1.5R2OSiO2 melts were tentatively determined from the specific heat capacities and bulk densities. In these results, the thermal conductivities were almost constant over the temperature range investigated. It was found that the thermal conductivity of AlO1.5Li2OSiO2 melt was larger than that of AlO1.5Na2OSiO2 melt. It was also found that the thermal conductivities were increased with AlO1.5 content in the content range from 0 to 16.8 mol% and that was decreased with increasing AlO1.5 content in the content range from 16.8 to 22.4 mol%.
