THERMAL AND ELECTRICAL CONDUCTIVITY OF GLASSES AND MELTS OF THE As-Ge-Se SYSTEM.

Temperature and concentration of glasses were studied as a factor of conductivity. It is shown that the thermal conductivity of glasses up to their softening temperatures depends weakly on the temperature since the high-temperature thermal capacity and the phonon propagation velocity are virtually independent of temperature. The temperature coefficient of the increase in thermal conductivity in the softening region of the glasses depends on the composition of the glasses and is determined by the rate of change in their thermal capacity.
