Abstract
The thermal diffusivity and specific heat have been measured at room temperature by laser flash method and AC calorimetry, respectively. Thermal conductivity has been determined by the product of density, thermal diffusivity and specific heat. The Debye temperature data have been collected from the measurements of ultrasonic method. For the direct calculation of these properties from glass composition, empirical equations that consist of compositional parameters Vi and Gi were obtained, where Vi is the packing density parameter and Gi is the dissociation energy of a single component oxide, respectively. Experimental results indicate that the calculated values using our proposed equations are in a good agreement with the measured values in many glasses studied in this work.
