Abstract

The phase composition and thermoelectric properties of solid solutions Pb₁₆Sn₂Ag₂Te₂₀ and Pb₁₄Sn₄Ag₂Te₂₀ are researched. Biphasic structure of the samples is installed, which providing to low values of thermal conductivity. Best samples have values of dimensionless thermoelectric figure of merit ZT ≈ 0,55.
