Abstract

The thermal effusivities of the AlO_1.5R₂OSiO（₂ R=Li, Na）melts were measured by the frontheating frontdetection laser flash method. The thermal conductivities of the AlO_1.5R₂OSiO₂ 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 AlO_1.5Li₂OSiO₂ melt was larger than that of AlO_1.5Na₂OSiO₂ melt. It was also found that the thermal conductivities were increased with AlO_1.5 content in the content range from 0 to 16.8 mol％ and that was decreased with increasing AlO_1.5 content in the content range from 16.8 to 22.4 mol％.
