The thermal conductivity, thermal diffusivity and volumetric heat capacity of monocrystalline AgCl and AgBr were measured simultaneously, by Advantageous Transient Plane Source method in the temperature range 77-350 K. Both thermal conductivity and thermal diffusivity follow Eucken's law in the temperature region studied. The heat capacity at constant pressure (C_p) determined from the volumetric heat capacity agrees with the calculated one at room temperature. The values of C_p obtained from this experiment along with the reported data as a function of temperature are also reported. The ratio of the thermal conductivity (λ) of AgBr and AgCl calculated from the Leibfried-Schlomann (LS) formula are in excellent agreement with the ratio λ_(AgBr)/λ_(AgCl) measured experimentally.The dielectric constant and loss factor, of these crystalline hallides, are also reported as a function of frequency in the range 100 Hz to 1 MHz at room temperature.
